▎ 摘　　要

NOVELTY - A graphene/silicon carbide reinforced alumina matrix composite has 4-8 %mass graphene-coated silicon carbide composite material and 92-96 %mass alumina matrix. The graphene-coated silicon carbide composite material is uniformly distributed in alumina matrix. The graphene-coated silicon carbide composite material is composed of 10-20 %mass graphene and 80-90 %mass beta -silicon carbide nanoparticles, and graphene sheet layer is coated on the surface of beta -silicon carbide nanoparticles. USE - Graphene/silicon carbide reinforced alumina matrix composite. ADVANTAGE - The graphene/silicon carbide reinforced alumina matrix composite has excellent compactness, electrical conductivity and mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene/silicon carbide reinforced alumina matrix composite.
