<P>PROBLEM TO BE SOLVED: To sinter a silicon carbide sintered body at a low temperature without forming a liquid phase. <P>SOLUTION: Mixture is prepared, wherein the mixture is made by mixing 1-10 wt.% of carbon or material which can be carbonized in terms of carbon as a carbon source, and 0.1-5 wt.% of boron or boron compound in terms of boron as a boron source, in silicon carbide powder. The mixture is sintered with a microwave at 1,800°C or higher. Thereby, even in such the low-temperature sintering, the sintered body of the silicon carbide powder, for example as shown in the figure, which is dense and suppresses abnormal grain growth, can be always obtained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
