| titleOfInvention | Insulating silicon carbide powder and its production |
| abstract | PURPOSE: To produce silicon carbide powder having excellent electrical insulation and thermal conductivity, by heating silicon carbide powder in nitrogen gas atmosphere in the presence of carbon and a boric acid compound, thereby depositing a boron nitride layer to the surface of the silicon carbide powder. n CONSTITUTION: The powder of silicon carbide is heat-treated at about 1,650W 2,300°C in nitrogen gas atmosphere in the presence of carbon and a boric acid compound to deposit a boron nitride layer having a specific thickness to the surface of the silicon carbide powder. The crystal form of the silicon carbide may be α or β, however, the purity of the silicon carbide is preferably about ≥90%. The carbon is e.g. acetylene black, channel black, etc., and the boric acid compound is e.g. boric acid, methyl borate, etc. If necessary, the attached impurities, etc. are removed by washing the treated silicon carbide powder with a hydrochloric acid solution, and the product is dried to obtain the objective silicon carbide powder. n COPYRIGHT: (C)1985,JPO&Japio |
