Extract

Current versions of the J.C.P.D.S. Powder Diffraction File Include some 26,000 standard patterns and this number is Increasing at the rate of around 1500 patterns per year. Although the actual number of patterns still represents a relatively small fraction of the total number of phases possible, it does include the majority of well known phases. A variety of search/match schemes have been designed under the auspices of the Joint Committee on Powder Diffraction Standards and these include data retrieval methods based both on hand and computer searching.

Since the majority of analytical problems involve multiphase materials, one of the greatest problems in qualitative identification is the “unscrambling” of the various phase patterns to allow matches to be made with standard patterns of pure materials.
