PBN
The chemical formula PBN belongs to the hexagonal crystal system. The purity can reach 99.999%. It is acid and alkali resistant, anti-oxidation, has good thermal conductivity, is dense, and can be processed. It is formed by chemical vapor deposition (CVD) of ammonia and boron halides under high temperature and high vacuum conditions. It is often used in semiconductor single crystal growth (VGF, LEC) crucibles, MOCVD heaters, satellite communication microwave tubes and high temperature applications. , High vacuum equipment insulation board.
