摘要： A silicon carbide sintered body containing not less than 0.03% by weight of boron, a total of not more than 0.3% by weight of metallic element impurities including the boron, not more than 1.0% by weight of free carbon, a total of not more than 0.15% by weight of non-metal impurities other than the free carbon, and the balance essentially consisting of silicon carbide, and having a density of not less 3.10 g/cm.sup.3. The sintered body is manufactured by heating a molding of a mixture containing a silicon carbide powder, a boron-containing sintering assistant, and a carbon-containing oxygen scavenger to a sintering temperature. The molded body is maintained at a temperature lower than the sintering temperature during the heating process until an oxide film covering the silicon carbide powder is substantially removed by the oxygen scavenger, and the molded body is then sintered at the sintering temperature under a non-pressurized condition.
