Phase Identification/Search Match for Powder Diffraction

• Two main parts to perform computer based search-match:

  • 1. Have a Powder Diffraction Database (buy or make your own)
  • 2. Search-match software that uses the above database to search

• Databases:

  • ICDD has the commercial powder diffraction database area cornered http://www.icdd.com
  • Alternative being developed is the Pauling File

• Nearly all Search-match programs are commercial:

• Refer to, "Available Search-Match Software" for a list of known software:

  • http://www.ccp14.ac.uk/solution/search-match.htm
  • Free Software:Brian Toby's "Portable Logic Program" (UNIX) and "MacDiff" for Apple Mac freeware by Rainer Petschick
  • Look out for the developing OpenXRD by Stefan Krumm (UNIX and Windows)
