Cubic Boron Nitride, Catalyst for Synthesizing Cubic Boron Nitride, and Process for Producing Cubic Boron Nitride

摘要

The invention In the manufacture of cubic boron nitride (CBN), uses a CBN synthesis catalyst which CBN composite surface of the catalyst components are covered with the organic material. By weight of the organic material added is from 0.01 to 50 parts by mass based on 100 parts by mass of the CBN synthesis catalyst ingredient and preferably, also is preferred as the organic acid is stearic acid and Ur La (or). In this CBN conversion factor and by using a catalyst composite (high volume), (111) plane is well developed and a sharp shape can be produced allows the incorporation of the catalyst component a small CBN productivity by simple processes and operations. ; Cubic boron nitride (CBN), CBN synthesis catalyst, organic
