Mechanical and Electrical Properties of Al₂O₃/SiC Nano-Composites

Abstract

Mechanical and electrical properties of nano-composite ceramic materials composed of Al₂O₃ matrix and nano-meter size SiC particles are described. The composites including less than 5vol% SiC particles have the same order of resistivity and dielectricity as those of the non-SiC material, while keeping highly improved-mechanical properties. The incorporation of 5vol% SiC into Al₂O₃ matrix might be promising for materials used under harsh circumstances.
