    摘要： Silicon oxynitride sintered body is obtained by sintering a base starting material mixture comprising silicon oxynitride componentand a solution of at least one alkoxide selected from alkoxides of at least one element selected from the group consisting of Al, Sc, Y and rare-earth elements.Fiber-reinforced ceramic sintered body is obtained by sintering the base starting material mixture further inclusing 5-40% by weight of SiC whiskers and/or .beta.-Si.sub.3 N.sub.4 whiskers, wherein alkoxide component is 0.5-30% by weight as oxides.The alkoxide component is deposited on the other material powders and calcined to provide well dispersed oxide layer on the powder surface which forms uniform matrix phase giving high density by sintering. Sintered bodies (with or without whiskers) have low deterioration at high temperatures.

    摘要： Diamond coating member is produced by a method comprising a first coating step in which the first diamond coating layer is closely formed on fine irregularity parts of a substrate having fine irregularities substantially without void left between them and the fine irregularities is engaged with the above first layer to coat the above substrate, and a second coating step in which the surface of the first coating layer is coated with a second diamond coating layer comprising diamond having a higher wear resistance than that of the first coating layer. The diamond coating member is excellent in adhesion between the diamond coating layer and the substrate and has high durability without having the diamond coating layer scaled off by mechanical shocks. It has high wear resistance and enables mass production without fluctuation in product quality.

    摘要： A process for producing a ceramic body suitable for surgical implantation that has high strength and toughness and good compatibility with bone material. A porous material is provided by semi-sintering a ceramic compact. The pores in the surface of the porous material are filled with a first powder of either tricalcium phosphate or apatite or both, or with a material of the fine powder and a powder of a material substantially the same as the material of the ceramic compact. The porous material is then fired at the sintering temperature of the ceramic compact. Following sintering, the surface of the porous material is coated with a fine apatite powder or a finally pulverized mixture of apatite and a calcium phosphate base frit. The resulting assembly is then fired at a temperature up to about 1,350.degree. C.
