PURPOSE:To obtain a sintered body of silicon carbide which contributes to lengthen the life of a molded body, and has high thermal conductivity, by containing the specified rate of boron content and one kind of content, at least, among Al, Be, Mg, and Ti, respectively. CONSTITUTION:When powder of silicon carbide is sintered, 0.05-5.50wt% of boron content converted into B is added, in order to increase denseness in a molded body of silicon carbide, and in addition, 0.05-5.50wt% of one content at least among Al, Be, Mg, and Ti converted into metal is added, in order to improve thermal conductivity of a sintered body. The effect is hardly recognized when less than 0.05wt% of Al, Be, Mg, Ti, or the like is added to a sintered body, while more than 5.50wt% of the above-mentioned content exerts adverse influence on the sinter molding and denseness is hard to be obtained in the sintered body. |
