HIGH PRESSURE DIFFRACTION FROM GOOD POWDERS, POOR POWDERS AND POOR SINGLE CRYSTALS

摘要

In this paper I describe the techniques we have developed over the last 10 years in Edinburgh to determine crystal structures at high pressure using high-quality powder samples, non-ideal powdered samples that possess texture or deviatoric stress, and poor quality single crystals. I illustrate the techniques with high-pressure data from a variety of samples.
