SiC POWDER, SiC SINTERED BODY, SiC SLURRY AND MANUFACTURING METHOD OF THE SAME

摘要

A method of manufacturing a silicon carbide (SiC) sintered body and a SiC sintered body obtained by the method are provided. The method includes: preparing a composite powder by subjecting a SiC raw material and a sintering aid raw material to mechanical alloying; and sintering the composite powder, wherein the sintering aid is at least one selected from the group consisting of an Al—C-based material, an Al—B—C-based material, and a B—C-based material. Accordingly, a SiC sintered body that can be sintered at low temperature, can be densified, and has high strength and high electrical conductivity can be prepared.
