Application of powder XRD

A basic, yet crucially important, application of powder XRD is in the identification ( fingerprinting ) of crystalline phases, based on the fact that different crystal structures give rise to distinct powder XRD patterns. Qualitative characterization of materials in this manner finds applications in many scientific disciplines (both academic and industrial), including quality control, polymorph screening, and the characterization of products from rapid throughput crystallization experiments [97, 98]. 

There are numerous references regarding X-ray powder data of HPOPs. For information on such data the reader is referred to an excellent review that was published by Whiyaker [21] in 1995. The purpose of this work is to present practical information of the application of powder XRD to the characterization of HPOP.
