CUBIC BORON NITRIDE, METHOD FOR PRODUCING CUBIC BORON NITRIDE, GRINDING WHEEL WITH CUBIC BORON NITRIDE, AND SINTERED CUBIC BORON NITRIDE COMPACT

摘要

The hexagonal boron nitride (hBN) is a method for producing cubic boron nitride to the held in the thermodynamically stable region of cubic boron nitride (cBN) in the presence of a catalyst material, a phase transition to hBN to cBN, the catalytic material is a lithium source, a magnesium source, and containing carbon atoms. Performance of cBN is improved despite the increased rate of phase transformation from hBN to cBN. ; Cubic boron nitride, hexagonal boron nitride and a catalyst material, phase transition rate
