<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a diamond-silicon carbide-silicon composite from diamond particles, and to provide a diamond-silicon carbide-silicon composite produced thereby. <P>SOLUTION: The method or manufacturing a diamond-silicon carbide-silicon composite comprises forming a work piece, heating the work piece, and controlling the heating temperature and heating time so that a certain desired amount of graphite is created by graphitization of diamond particles, to prepare an intermediate, and infiltrating silicon into the intermediate, to thereby produce a body of material which comprises 20-75% by volume of diamond particles, at least 5% by volume, preferably more than 15% by volume of silicon carbide, and silicon, and has a Young's modulus exceeding 450 GPa. <P>COPYRIGHT: (C)2009,JPO&INPIT |
