cubic boron nitride powder

Cubic Boron Nitride Powder is synthesized from hexagonal boron nitride and a catalyst at high temperature and pressure. Cubic Boron Nitride Powder is another new product after the advent of synthetic diamond. Cubic boron nitride has high hardness, thermal stability and chemical inertness, as well as excellent infrared transmittance and wide band gap. The hardness of Cubic Boron Nitride Powder is second only to diamond, but the thermal stability of cubic boron nitride is much higher than that of diamond, and it has greater chemical stability to iron-based metal elements. The grinding performance of the abrasive tool prepared by Cubic Boron Nitride Powder is very good, not only can it be competent for the processing of difficult-to-grind materials, improve the productivity, but also effectively improve the grinding quality of the workpiece.

Cubic Boron Nitride（CBN） is a superhard material whose hardness is second only to diamond and much higher than other materials. Cubic Boron Nitride is widely used in sawing tools, grinding tools, drilling tools and cutting tools. Diamond is easy to be oxidized at high temperature, especially with good affinity with iron-based elements, so it is not suitable for iron-based element ferrous metal processing. Cubic Boron Nitride has good chemical stability, especially compared with diamond, and does not chemically react with iron group elements at temperatures as high as 1100-1300 °C, so it is especially suitable for processing ferrous metal materials.
