<P>PROBLEM TO BE SOLVED: To solve a problem that, though there are methods by using elements Al, B and C or an Al<SB>8</SB>B<SB>4</SB>C<SB>7</SB>compound as sintering aids for sintering means to make SiC sintered compact, however the elements Al, B and C hardly form a suspension causing trouble in mixing, while the Al<SB>8</SB>B<SB>4</SB>C<SB>7</SB>compound is difficult to be synthesized, or actually cannot be synthesized as a single phase. <P>SOLUTION: Powder molding and sintering have caused drawbacks in conventional processes. The inventors have found out a sintering aid Al<SB>3</SB>BC<SB>3</SB>compound which is stable at high temperatures. Further it easily forms a suspension with SiC powder so that it facilitates the molding process and sintering process. <P>COPYRIGHT: (C)2009,JPO&INPIT |
