Cubic boron nitride in a nitrogen gas through the vacuum heat treatment is carried

Cubic boron nitride because of its high hardness, high thermal stability and high chemical inertness is widely used as an abrasive, (based on the requirements of different conditions of use, to be treated on its particle surface to serve as a polishing powder,  polycrystalline diamond , grinding paste, polishing liquid and resistant lubricant oil dedicated engine running through the cubic boron nitride in a nitrogen gas, a vacuum heat treatment, Synthetic diamond  different temperature and time hBN into cBN law, for the future in the ultra-fine processing polishing powder, polishing paste, polishing liquid and wear lubricants, engine running dedicated lay the foundation for the application of oil.
