KINETICS OF SOME SOLID STATE REACTIONS AT HIGH PRESSURE.

Abstract

The thesis comprises a kinetic study of some solid state reactions, and includes the influence of both temper ature and high pressure on the rates of transformation. The following polymorphic reactions were investigated with temperature to 700 C and pressure to 100,000 bars: Si02-quartz to Si02-coesite; Si02-cristobalite to Si02coesite; Si02-cristobalite to Si02 quartz; crystallization of Si02-glass; crystallization of BeF2-glass; crystallization of Ge02-glass; and Ge02-quartz to Ge02-rutile. In addition, the reverse transformation of both Si02coesite and BeF2-coesite was investigated at high temperature and ambient pressure. (Author)
