Zusammenfassung:PURPOSE:To produce high-quality finely granulated silicon carbide, neither leaving a silica component nor preparing whiskers as a by-product, in excellent operating efficiency. CONSTITUTION:In a method of converting a mixed raw material comprising silica and a carbon material into silicon carbide powder by reduction carbonization reaction of silica in an inert atmosphere at 1,300-2,000 deg.C, carbon black having
