Study, Design and Fabricate a Cold Crucible System

Abstract

The objective of this program was to conduct a study, design and fabricate a cold crucible system for the synthesis and crystal growth of refractory semiconductors and oxides. A theoretical analysis of the cold crucible relating the properties of the material to the electrical characteristics of the cold crucible was completed. The thermal analysis, which includes thermal modeling by means of a computer technique, was also completed. A detailed analysis of the RF power control system necessary to provide the desired stability for crystal growth was also carried out. Using a 50 Kw (4-7 megahertz) RF power supply the cold crucible assembly was tested and kilogram melts of zirconia (melting point 2690C) were successfully contained.
