An Investigation of the Crystalchemistry and Thermochemistry of Selected Mineral Systems.
Abstract
A computer-controlled travelling Laue x ray camera and small rapid response furnace system was designed, constructed and operated for the study of phase transitions in solid state systems. The camera is capable of continuously monitoring crystallographic phase changes occurring in small single crystal samples over temperature range from 100 to 1000K. Extensive studies of complex structural changes in natural crystals to tridymite were completed. Some preliminary experiments were also made with single crystals of CdS and CdTe. All materials were characterized with transmission electron microscopy. Defect and strain distributions in CdS and CdTe crystal were also examined with synchrotron white beam topography. This report gives a brief overview of results accomplished. It includes a list of papers and abstracts published during the course of the research. Keywords: Phase transitions, Continuous x ray diffraction, Tridymite, X ray topography, Electron microscopy.
