Pyrolytic boron nitride (PBN) belongs to the hexagonal crystal system, with a purity of up to 99.999%. It is resistant to acids and alkalis, antioxidant, has good thermal conductivity, is dense and processable. It is formed by chemical vapor deposition (CVD) of halides of ammonia and boron under high temperature and high vacuum conditions. It can be used to prepare PBN plates as well as directly produce final PBN products such as crucibles, boats and coatings.
