Introduction of Pyrolytic Boron Nitride. PBN is a high purity ceramic that has excellent chemical resistance and high strength at high temperatures. Shin-Etsu Chemical was the first to produce PBN in Japan. PBN is used to make compound semiconductors and molecular beam epitaxy. There are many uses for PBN, including high functional PG/PBN heaters in semiconductor fields and CIGS based thin films for photovoltaic power production.

Pyrolytic Boron Nitride. Also known as Pyrolytic Boron Nitride (or PBN), Chemical Vapour-deposition Boron Nitride (or CVD-BN), Pyrolytic Boron Nitride (or Pyrolytic Boron Nitride) and Chemical Vapour-deposition Boron Nitride (or CVD-BN). This is a type of boron-nitride that has been prepared using high-temperature pyrolysis and chemical vapor deposition. This is very similar in structure to graphite or diamond, which are the crystal forms of carbon. Hexagonal and hexagonal graphite have many similarities. Hexagonal and hexagonal graphite are therefore called white graphite. Although the pyrolytically boron-nitride is hexagonal, it does have a small amount of disordered layers. PBN prepared through chemical vapor deposition has a high purity and can exceed 99.9%.

Structure and morphology for PBN. Pyrolytic Boron Nitride (PBN), is a typical layered product that belongs to the hexagonal structure. Inter-layer and intra-layer spacings are quite different. The inter-layer spacing of atoms is 3.33 A and the intra-layer spacing is 1.45 A. PBN's structure is composed of alternating N and B atoms within the layer and along its C axis. The stacking method used to build it is ababab . The stacking faults in the PBN can be seen under a microscope. This results in a layer spacing that is greater than the theoretical. PBN is oriented in the C axis direction, which results in a high degree layer orientation. The preferred orientation direction for PBN is the C axis.
