Abstract

This final report of a program of research on growth and deformation processes in spinel includes a description of an R. F. plasma growth facility and its operation. The main conclusion from the growth experiments is that the instability of spinel at its melting point precludes the growth of large stoichiometric single crystals by direct fusion. Alternative techniques are discussed. The effect of heat treatment on the microindentation behavior and room temperature compressive strength of alumina-rich spinel single crystals is discussed. Some high temperature strength data on alumina-rich spinel are included.
