ICDD PDF-4+ 2012 Instructions

Setting up Preferences
The next step is to ensure that the PDF-­‐4+ 2012 software is set up appropriately for the
experiment that you performed.
1. Click on the ‘PDF-­‐4+ 2012’ icon on the desktop of the computer to launch the
software, if not already running.
2. At the top of the screen, click the Edit menu, then choose Preferences.
3. In the PDF Card tab, ensure that the ‘Wavelength’ matches that of your experiment.
4. Click on the Simulated Profile tab and make sure that again the Type and Anode
match your experiment (i.e. Type = Ka1 or Ka1+2 and Anode = Co, Cu or Mo as
appropriate).
5. Also on the Simulated Profile tab, check how the ‘Profile’ is being calculated for
simulated line shapes. An easy way to simulate sharper Bragg lines is to use a larger
‘Crystallite Size’ with ‘Mean Crystallite Diameter’ of 500.0 nm or higher; conversely,
using a smaller ‘Mean Crystallite Diameter’ will calculate a broader line shape.
6. At the bottom of the Simulated Profile tab, you can also select the Ranges displayed
for simulated profiles.
7. On the SIeve+ tab, set the desired Search Method (typically Hanawalt), Search and
Match Windows (typically 0.18), Lowest Allowable GOM (1000-­‐2000, lower will allow
more ‘false positives’) and Wavelength (as appropriate)
8. Click OK.
