As an engineering material, it has been widely used in the processing industry of ferrous metals and their alloys. At the same time, it has been used in a series of high-tech fields with its excellent thermal, electrical, optical and acoustic properties, becoming a functional material with development prospects.

[0003] Cubic boron nitride Cubic boron nitride powder is used in precision grinding, lapping, polishing and super finishing to achieve high-precision machining surface. It is suitable for binder systems such as resin, metal, ceramic, etc. It can also be used to produce polycrystalline composite sheet sintered bodies. It can also be used as loose abrasives and grinding pastes.
