摘要：
A sintered compact of cubic boron nitride is made by adsorbing and/or diffusing 0.005 to 1.000 percent by weight of water into a boron nitride compact containing alkaline earth metal boron nitride as a catalyst. The so prepared compact is then subjected to a treatment under high pressure at a relatively low temperature to form a dense cubic boron nitride sintered compact of high purity.
