摘要
A CBN synthesis catalyst containing a CBN synthesis catalyst component coated with an organic substance is used for producing cubic boron nitride (CBN). The amount by mass of the organic substance is preferably contained 0.01 to 50 parts by mass based on 100 parts by mass of the CBN synthesis catalyst component. The organic substance is preferably stearic acid and/or lauric acid. By use of such a CBN synthesis catalyst, a CBN crystal which has a sharp shape, with the (111) place being developed, and which contains a small amount of a catalyst component(s) incorporated into CBN can be produced at high productivity (percent transformation (high yield)) in a simple manner and operation.
