    摘要： A colorless and transparent, substantially inclusion-free diamond crystal which can be applied to decorative uses and optical parts is synthesized by a process using a temperature gradient method in an ultra-high pressure apparatus. This process comprises using, as a solvent for the growth of the crystal, at least one metal selected from the group consisting of Fe, Co, Ni, Mn and Cr (at least two metals in the case of containing Fe) and as a nitrogen getter for the removal of nitrogen in the solvent, at least one metal selected from the group consisting of Al, Ti, Zr, Hf, V, Nb and Ta in a proportion of 0.5 to 7% by weight (at most 2% by weight when using only Al) to the solvent metal.

    摘要： Diamond abrasive grains are produced by a process which comprises steps of: regularly arranging a plurality of diamond crystal seeds on a first metal solvent plate, stacking a second solvent metal plate on the first solvent metal plate so that the diamond crystal seeds are sandwiched by the first solvent metal plate and the second solvent metal plate, and stacking a graphite raw plate on the second solvent metal plate to construct a production system for the diamond abrasive grains, heating the system or heating the system with pressurizing to a temperature above a solvent metal-graphite eutectic point through a temperature and pressure condition in which diamond is thermodynamically unstable to establish a temperature and pressure condition in which diamond is thermodynamically unstable, and heating the system or heating the system with pressurizing to establish a temperature and pressure condition in which diamond is thermodynamically stable and maintaining said condition.

    摘要： A diamond sintered body conventionally used in a cutting tool or the like includes an iron group metal element as a sintering aid, and therefore has a problem in heat resistance. A diamond sintered body not including the iron group metal, on the other hand, does not have sufficient mechanical strength to be used as a tool material, and also does not have conductivity, which makes electrical discharge machining impossible, and thus processing thereof is difficult. A diamond polycrystalline body having high heat resistance and mechanical strength and having conductivity enabling electrical discharge machining is obtained by using only an amorphous or fine graphite-type carbon material as a starting material, adding boron thereto and concurrently performing conversion into diamond and sintering in an ultra-high pressure and temperature condition.

    摘要： A cubic boron nitride sintered body has sufficient strength, hardness, heat resistance and heat dissipativity for serving as a cutting tool. A method of preparing a cubic boron nitride sintered body involves preparing a low-pressure phase boron nitride as a starting material by reducing a compound containing boron and oxygen with a compound containing nitrogen and carbon. Then, the low-pressure phase boron nitride starting material is directly converted to a cubic boron nitride sintered body by subjecting the starting material to a high temperature and a high pressure. In the obtained cubic boron nitride sintered body, the ratio I.sub.220 /I.sub.111 of X-ray diffraction intensity I.sub.220 on the (220) plane relative to X-ray diffraction intensity I.sub.111 on the (111) plane is at least 0.1.

    摘要： A cubic boron nitride sintered compact is produced by adding to atmospheric pressure type boron nitride, a cubic boron nitride synthetic catalyst and 0.01 to 5.0 percent by weight of a hydroxide of an alkaline earth metal to form a mixture. Then, the mixture is subjected to a high temperature/high pressure treatment under a thermodynamically stable pressure condition for cubic boron nitride, whereby the atmospheric pressure type boron nitride is converted to cubic boron nitride under the action of the cubic boron nitride synthetic catalyst. The cubic boron nitride sintered compact thus obtained contains 0.01 to 5.0 percent by weight of an oxide of the alkaline earth metal only in triple points between the cubic boron nitride grains. The cubic boron nitride grains are densely bonded with each other.
