A STUDY OF FUNDAMENTAL MECHANICAL PROPERTIES OF CERAMIC SINGLE CRYSTALS.

Abstract

The interrelationships of strength, crystal thickness and boron concentration in silicon carbide have been evaluated. Definite trends toward higher strength in both thin and pure silicon carbide crystals are shown. Neither purity nor thickness has a significant effect on Young's modulus of elasticity of silicon carbide. Similar relationships between purity and micro hardness of silicon carbide are being evaluated. Grinding and lapping of silicon carbide crys tals, if confined to the face loaded in com pression, have no significant effect. (Author)
