摘要： A powder of at least one of TiB.sub.2, ZrB.sub.2 and HfB.sub.2 is mixed with at least one of Ti, Zr, Hf, TiB, ZrB and HfB, or with at least one of Ti, Zr, Hf, TiB, ZrB and HfB and a powder of boron, to prepare a mixed powder which can form a sintered product having a boron content of 65 to 67 atom %. Alternatively, a powder of at least one of Ti, Zr, Hf, TiB, ZrB and HfB is mixed with a powder of boron to prepare the mixed powder. The mixed powder may further contain up to a maximum of 30% by weight of a powder of AlN. Then, the mixed powder is sintered to make metal diboride ceramics. The lower-melting metal or compound which the mixed powder contains melts to form a liquid phase and enables the manufacture of a sintered product of high density by a customary sintering operation employing a low temperature. The sintered product having a boron content of 65 to 67 atom % consists solely of metal diboride crystals having a structure of the hexagonal system.

摘要： A novel method is disclosed for the preparation of a silicon carbide-based composite ceramic body reinforced with carbon fibers having an outstandingly high mechanical strength. The method comprises impregnating carbon fibers with a mixture of fine silicon particles and a thermosetting resin such as a phenolic resin to give a carbon fiber compact body impregnated with the mixture, which is then subjected to a heat treatment at about 1400.degree. C. in an inert atmosphere so that the thermosetting resin is thermally decomposed to produce free carbon capable of reacting with the silicon particles without affecting the carbon fibers embedded in the matrix due to the preferential reactivity of the silicon particles with the free carbon produced from the resin thus not to decrease the recinforcing effect of the carbon fibers.
