CHARACTERIZATION OF MICROCRYSTALLINE PHASES IN GLASS-CERAMIC MATERIALS.

Abstract

The report is concerned with the characterization of the high-quartz and keatite solid solutions which occur as important principal microcrystalline phases in glass-ceramic materials. The properties of these phases, sometimes very unusual such as negative thermal expansion, contribute significantly to the overall properties of glass-ceramic bodies. It was the primary objective of this research to determine the structures and chemical compositions of the solid solution phases, including details of crystal lattice defects in terms of specific order-disorder phenomena on a sub-micro, domain or unit cell scale.
