MATERIAL PROPERTIES OF A SINTERED ALPHA-SIC

A self-consistent, single-valued representation of the major physical, mechanical, and thermal properties of a sintered alpha-SiC is present ed. This comprehensive set of properties is achieved by focusing on a narrowly defined material specification in which boron and carbon are used as sintering aids to produce a dense ceramic (greater than or equ al to 98% of the theoretical maximum density) with a grain size of (6/-2) mu m. Such a representation is highly desirable in applications o f concurrent engineering practices and for the increasing use of elect ronic processing of product specifications.
