    摘要： [Problem] This invention aims to provide a production method of a fine grain polycrystalline diamond compact which is suitable for finishing cutting tool materials and/or ultra-precision machining tool materials. In the method, a freeze-drying process for preventing the growth of secondary particle formation is unnecessary, and an aid does not need to be mixed in advance.[Means for Resolution] Disclosed is a following production method of a fine grain polycrystalline diamond compact. Each of carbonate and a C—H based organic compound which is a solid at room temperature, is sandwiched between diamond powder layers to stack them up in layers in a Ta capsule. Particle size of the diamond powder is 4 μm or less in average; and the organic compound is preferably one or more selected from among polyethylene, polypropylene and polystyrene. The layers in the capsule are sintered under the conditions of a pressure of 7.7 GPa or higher and a temperature of 2000° C. or higher.In the method, diamond powder as a raw material for sintering is prepared without any freeze-drying process; also the pre-mixture of an aid and an oxalic acid dihydrate which is a hazardous material, is not required.

    摘要： A method for producing a highly uniform and highly dense sintered cubic boron nitride compact having high hardness by sintering at a milder condition without a binder, is provided. The method includes deflocculating secondary particles in cubic boron nitride starting powders by dispersing the starting powders in a solution of a deflocculant; molding the green compact after removing the solution of the deflocculant from the starting powders; and then sintering the green compact in the presence of a supercritical fluid source in a supercritical state by pressing and heating the green compact together with the supercritical fluid source. The supercritical fluid source can be one or more selected from a group consisted of polyvinylidene chloride, polyvinyl chloride, polyethylene, polypropylene, polystyrene, a polyester and an ABS resin. In the sintering, the pressure is 5 GPa or higher, and the temperature is 1400° C. or higher. According to the method, a highly uniform and highly dense sintered cubic boron nitride sintered compact having high hardness, can be obtained.
