The purpose of the program Crystal Cracker is to provide various manual techniques for solving powder diffraction patterns, in a modern user-friendly program that is free of charge. The program was written from scratch by Kurt Leinenweber, in Visual Basic. It is distributed as an executable file. It should run on any Windows system that includes support for programs written in Visual Basic 6.0.
Version 189. Lattice-fitting of cubic phases and 2 theta fitting added to energy dispersive data. Opening of jcpds files from APS Sector 13 added. The peak fitting routines are primitive but quick to use.
Version 180, January 6, 2004. A reading format error in GSAS files was fixed (thanks to Jeff Post for noticing the problem with some GSAS files). When the "number of banks" were shown for each point, the program did not read the data correctly.
Version 178; December 5, 2003. The program was prepared for a beam time at Argonne. The ability to read CHI files from Sector 13 was added. Small two-theta angles were allowed. As a bonus, energy-dispersive capabilities were added using an MCA file sent by Yanbin Wang. Certain bugs in the storage of patterns and unit cells were fixed, and more unit cells were added to the little database UnitCell.ucl.
XRD is a non-destructive test method used to analyze the structure of crystalline materials. XRD analysis, by way of the study of the crystal structure, is used to identify the crystalline phases present in a material and thereby reveal The chemical composition information. JCPDS does not exist now. It has not existed since 1978. It is now known as ICDD. These particular files have never been, are not, and never will be free; it a commercial only database. There are other free databases, however. Vikas has given you a starting point.
COD is an open-access database, and you can freely obtain all data contained in it. You can download cif files and then you can use mercury to plot structure models and save reflection list and xrd calculated pattern.
Match! is an easy-to-use software for phase analysis using powder diffraction data. It compares the diffraction pattern of your sample to a database containing reference patterns in order to identify the phases which are present. Additional knowledge about the sample like known phases, elements or density can be applied easily. In addition to this qualitative analysis, a quantitative analysis (using Rietveld refinement) can be performed as well. You can easily setup and run Rietveld refinements from within Match!, with the actual calculations being performed automatically, using the well-known program FullProf (by J. Rodriguez-Carvajal) in the background. Match! provides a gentle introduction into Rietveld refinement, from fully automatic operation to the "Expert" mode. The software runs natively on Windows, macOS and Linux.
As reference database, you can apply the included free-of-charge COD database, use any ICDD PDF product, and/or create a user database based on your own diffraction patterns. The user database patterns can be edited manually, imported from peak files, calculated from crystal structure data (e.g. CIF files), or imported from your colleague's user database. A list of Match!'s most prominent features can be found here.
There are several versions of the formats used for JCPDS files. Versions 1, 2 and 3 used a fixed format, where a particular entry had to be in a specific location on a specific line. Versions 2 and 3 were used only by Dan Shim. Version 4 is a "keyword" driven format. Each line in the file is of the form:
The following keywords are currently supported: COMMENT: Any information describing the material, literature references, etc. There can be multiple comment lines per file. K0: The bulk modulus in GPa. K0P: The change in K0 with pressure, for Birch-Murnaghan equation of state. Dimensionless. DK0DT: The temperature derivative of K0, GPa/K. DK0PDT: The temperature derivative of K0P, 1/K. SYMMETRY: One of CUBIC, TETRAGONAL, HEXAGONAL, RHOMBOHEDRAL, ORTHORHOMBIC, MONOCLINIC or TRICLINIC A: The unit cell dimension A B: The unit cell dimension B C: The unit cell dimension C ALPHA: The unit cell angle ALPHA BETA: The unit cell angle BETA GAMMA: The unit cell angle GAMMA VOLUME: The unit cell volume ALPHAT: The thermal expansion coefficient, 1/K DALPHADT: The temperature derivative of the thermal expansion coefficient, 1/K^2 DIHKL: For each reflection, the D spacing in Angstrom, the relative intensity (0-100), and the H, K, L indices.
The following is an example JCPDS file in the Version 4 format: VERSION: 4 COMMENT: Alumina (JCPDS 0-173, EOS n/a) K0: 194.000 K0P: 5.000 SYMMETRY: HEXAGONAL A: 4.758 C: 12.99 VOLUME: 22.0640 ALPHAT: 2.000e-6 DIHKL: 3.4790 75.0 0 1 2 DIHKL: 2.5520 90.0 1 0 4 DIHKL: 2.3790 40.0 1 1 0 DIHKL: 2.0850 100.0 1 1 3 DIHKL: 1.7400 45.0 0 2 4 DIHKL: 1.6010 80.0 1 1 6 DIHKL: 1.4040 30.0 2 1 4 DIHKL: 1.3740 50.0 3 0 0 DIHKL: 1.2390 16.0 1 0 10
Jade is the program that lets you manipulate powder diffraction data, including finding peaks, calculating d-spacings, exporting data, and even matching peaks to particular powder diffraction file patterns using the PDF peak search and match database. This page covers only basic things: reading diffraction files, modeling the background, Kα2 peak stripping, and peak finding.
The search and match program is quite complicated, and the help file is not that helpful. However, the idea is to set up database subsets of not more than 500 minerals (a software license restriction), and to search in those subsets. Some subsets have been made already, Cements.plf is the one displayed here. You can compile lists by chemical elements, chemical formulae, crystal structure, and other ways. The learning curve is steep, but if you work through it, it can be a real time saver.

Version 7.5.0 March 9, 2009IntroductionPlot85 is used to plot and analyze energy-dispersive diffraction data created by the SAM85 or MCA data collection programs. It can be used to determine the channel number, energy, or d-space for any diffraction peak, either by pointing to the peak, or to fit it using GPLS. Reference data can be imported in several file formats, described below: .HKL, .JCPDS, .POW. If the diffraction data is from NaCl, the pressure and differential stress can also be calculated.Plot85 for Windows is a port and upgrade of Plot85 for VMS. Its upgrades include the ability to directly read APS data, read data created by multiple detectors (up to 4), and includes as subroutines Celrf (a unit cell refinement program written by Charlie Prewitt) and XPOW (a program written by Bob Downs and Kurt Bartelmehs which calculates powder-pattern data from crystallographic data).To install and run PLOT85, see INSTALLATION, at the end of this document. The program will run (with somewhat limited features) if you simply click on the PLOT85.EXE file.When the program starts, it will look for an energy calibration file (DEFAULT.EDF) and a list of hkls for some standards (STANDARD.HKL) in two locations. It will first look in the location specified in the start in selection in the shortcut (see INSTALLATION). If it cannot find the file there, it will look in another, arbitrary directory you may define using an environment variable. Contents (Number in parentheses is the approximate page number in the printed version) Flow Chart (1) XPOW (4) CELRF (9-10) Reference File (16) Installation (18-19) JCPDS (5-6) Peak Search (10-13) UTILITIES (16-17) Shortcut (19) File (2-3) FLUORESCENCE (6-7) Calibration (13-15) Operations (17-18) Version History (19-21) Standards (4-5) GPLS (7-9) Birch Murnaghan (15-16) Flow Chart Starting Program and Layout Opening the program gives you a window with 2 sub-windows, the Text window (labeled Plot85 Text Window), and the Plot window (Labeled Plot85 Main Graphics Window, # 1). The "focus" window will be the Plot window. Move it out of the way, and you will see what is displayed below:
The filename of the program (which normally includes the version number) is displayed in the title bar of the main window. The text window displays what is happening during the running of the program. For some operations, it must be in focus, and for others it must not. If Plot85 finds a calibration file, then it is displayed; if it finds the Standard.hkl file, then a list of the standards is also displayed. Nothing appears in the Plot window, because no datafile has been selected nor has it been plotted.
The STANDARDS menu lists the materials listed in the current STANDARD.HKL file (if no HKL file has been read in, then this menu will be blank). The entry "No Standard" removes the current selection from memory, so it isn't plotted. The entry "New Cell" allows you to enter new cell parameters (i.e. to simulate high temperature and/or pressure). The new lines are calculated. Although all six cell parameters are displayed, only the ones required for the current symmetry need be entered; e.g. for cubic, only a needs to be entered. The entry "Set Cell Increment" allows you to change the unit cell parameters a, b, and c using hot keys "I' and "i". Entering "I" with the graphics window active will increase any or all of a, b, and c by one increment and redraw the plot', "i" will decrease it. Default values are .01 (1%). If you get the message "incorrect data format", you probably used a STANDARD.HKL file without the commas in the second line of one of the standards. The format of the STANDARD.HKL file is described below: NaCl 5.6402,,,,,,1 1,1,1,3.26,13.,2 2,0,0,2.821,100.,1 2,2,0,1.994,55.,3 2,2,2,1.628,15.,2 4,2,0,1.261,11.,4 999,0,0,0,0 MgO 4.231,,,,,,4 1,1,1,2.431,10. 2,0,0,2.106,100. 2,2,0,1.489,52. 3,1,1,1.216,4. 2,2,2,1.216,12. 4,0,0,1.0533,5. 999,0,0,0,0 Al2O3 4.758,4.758,12.99,90.,90.,120.,0 0,1,2,3.4802,75. 1,0,4,2.55105,90. 1,1,0,2.3796,40. 1,1,3,2.0855,100. 0,2,4,1.7401,45. 1,1,6,1.6015,80. 1,2,4,1.4046,30. 0,3,0,1.3739,50. 1,0,10,1.2391,35. 1,1,9,1.2343,8. 2,2,0,1.1898,8. 2,2,3,1.1470,6. 3,2,1,1.1255,6. 2,0,10,1.0990,9. 999,0,0,0,0 Co57 5.6402,,,,,,0 1,1,1,14.413,25. 2,0,0,122.0614,100. 2,2,0,136.4743,20. 2,2,1,6.4,30. 2,2,2,21.123,10. 4,2,0,23.859,5. 999,0,0,0,0 Each material has four types of entries: an identifying title, the cell parameters, a list of diffraction lines, and a terminating line.The first line is somewhat arbitrary, but all important information should be included in the first 10 or so characters. It is displayed on the plot.The second line consists of the six cell parameters, followed by a code for pressure measurement. That code is 1 for NaCl, 4 for MgO, and 0 for anything else. Enough cell parameters must be entered to define the cell. If the angles are left blank, a value of 90° is assumed. All entries must be comma-separated.The remaining lines consist of h, k, l, d, I, and O, where h, k, and l, are the Miller indices (integer format), d is the d-space in angstroms, I is the intensity (100.0 being the maximum, decimal notation), and O is an orientation parameter for stress calculation. This line of data can also be used for non-diffraction lines (such as gamma or fluorescence lines) by entering the energy in KeV in place of d. If that number is greater than 10, it is assumed to be an energy. See the 4th entry, Co57. "Dummy" h,k,ls must also be entered.The list is ended with a dummy diffraction line, with 999 as h.The maximum number of lines is 20; the first ten are identified by the single numeric key 1-0; the next ten are the same keys, shifted: ! through ).If you get a message stating that the STANDARD.HKL file may be incorrect, the most likely reason is that the individual cell parameters are not in the correct format.Pressure Measurements using the Decker EOS for NaCl can only be done if NaCl is loaded as the standard in the above menu. XPOW The XPOW menu allows you to create a theoretical powder pattern from a .POW file. This should be used to display your sample data instead of the STANDARD.HKL file. It uses a modification of the XPOW program, written by Bob Downs and Kurt Bartelmehs. For reference, see Downs et al. (1993) American Mineralogist 78, 1104-1107. You will have to get a .POW file. Get the XPOW program from =software and download the executable and sample datafiles for XpowWin. The .POW files are the sample data files. To modify them, you will need to know the cell parameters, the space group, and all the positional and occupancy parameters for the structure. Put your selected and/or modified .POW file in your data directory. The XPOW menu has selections:Read File (this must be done first).Print - prints on the screen a list of h,k,l, and d for up to 40 strongest linesNew Cell - same as New Cell in the Standards menuSet Cell Increment - same as Standards menuPlot lines - adds the new reference lines to the current plotOne acceptable format for the .POW file is shown below: corundum: standard at U of Arizona Mo 0 50 4.7608 4.76089 12.9957 90 90 120 R-3c Al 0 0 .355 O .306 0 .25 stop corundum: Zachariasen: (1928) Skrifter Utgitt Av Det Norse Videnskaps-Akademi Mo 0 70 4.759 4.759 12.991 90 90 120 R-3c Al 0 0 .355 O .306 0 .25 One .POW file may have more than one entry (as in the example above), but only the first will be used. An entry consists of a title, radiation information (ignored, but must be present), the six cell parameters and the space-group, and one line per atom with the chemical symbol and the fractional position of that atom listed. JCPDS The JCPDS menu allows you to input a reference file in the APS .JCPDS format. The menu has selections: Read file / Plot Lines - Reads a JCPDS file from any location (default is the same folder as the data), and plots the lines. Plot Lines - Persistent. - This option replots the lines every time you change detectors, files, or expanded region. It must be turned off if you want to use the Standards file. Plot Lines Display - prints on the screen the portions of the selected JCPDS file used by this program. New Cell - allows you to enter new cell parameters (i.e. to simulate high temperature and/or pressure). The new lines are calculated. Although all six cell parameters are displayed, only the ones required for the current symmetry need be entered; e.g. for cubic, only a needs to be entered. Set Cell Increment - Entering "I" with the graphics window active will increase a, b, and c by 1% and redraw the plot; "i" will decrease it. Set Cell Increment allows you to change the increment. Plot lines - adds the new reference lines to the current plot Read PDF2 - reads PDF2 output from Brian Toby's LOGIC program. LOGIC, in turn, reads data from the ICDD PDF2 database, which much be licensed ($$). Write JCPDS - exports data from PDF2 to our .JCPDS format. Profile Setup Two formats of the JCPDS file can be used; the current (version 4) format is be shown below (note: version 4 refers to JCPDS file version, not PLOT85 version): VERSION: 4 COMMENT: Alumina (JCPDS 0-173, EOS n/a) K0: 194.000 K0P: 5.000 SYMMETRY: HEXAGONAL A: 4.758 B: 0.0000 C: 12.99 ALPHA: 0.0000 BETA: 0.0000 GAMMA: 0.0000 VOLUME: 22.0640 ALPHAT: 2.000e-6 DIHKL: 3.4790 75.0 0 1 2 DIHKL: 2.5520 90.0 1 0 4 DIHKL: 2.3790 40.0 1 1 0 DIHKL: 2.0850 100.0 1 1 3 DIHKL: 1.7400 45.0 0 2 4 DIHKL: 1.6010 80.0 1 1 6 DIHKL: 1.4040 30.0 2 1 4 DIHKL: 1.3740 50.0 3 0 0 DIHKL: 1.2390 16.0 1 0 10 For JCPDS version 4 files, each line begins with a keyword.All entries are read by PLOT85, but not all are used. The parameters Ko, KoP and AlphaT are used in the Birch-Murgnahan equation of state option. As in the STANDARD.HKL and XPOW files, each diffraction line is identified on the plot with a single symbol. They are:Lines 1-10: 1 2 3 4 5 6 7 8 9 0Lines 11-20 (shifted versions of 1-10):! @ # $ % ^ & * ( ) XPOW and JCPDS formats allow 20 additional lines:Lines 21-30: - = \ [ ] ; ' , . / Lines 31-40 (shifted versions of 21-30):_ + | { } : " < > ? JCPDS version 4 files are also used by the MCA program for calibration and pressure measurement. FLUORESCENCE The Fluorescence menu allows you to display the 4 strongest K X-ray fluorescence lines from any element. The menu has selections: The last 5 elements selected will be added to the menu list for easy recall. List elements Add element Plot lines - adds the new reference lines to the current plot Plot CO57 - plots the three gamma calibration lines from Co57 (line at 136.4743 keV is usually out of range). A preselected list of 6 elements Up to 4 newly added elements If you add an element, that element will be added to the bottom of the list. When 4 new elements have been added, the 5th replaces the first of the newly added element list. Those on the preselected list remain unchanged. If you want to display another line, select another element and re-plot it. If you press S or s before you replot the fluorescence lines, the old ones will be removed before the new ones are plotted. If you don't, the new ones will be added. GPLS GPLS SetupThe GPLS General Setup menu controls various parameters in the General Program for Least Squares fitting routines. The Auto Peakfit Setup menu makes use of the multiple data set fitting routines which use GPLS. Run Auto Peakfit is used after the previous two setup menus. In the GPLS setup menu, most of the defaults will remain unchanged. 2b1af7f3a8
