Pyrolytic Boron Nitride Description

Pyrolytic boron nitride (PBN) has raw materials with much higher purity level than normal boron nitride ceramic. It is a high purity material with no porosity which could be deposit on all kinds of graphite shapes by chemical vapor deposition (CVD). Although pyrolytic boron nitride could be deposited on various materials, it is usually used on graphite only, since the temperature of this CVD process is extremely high and the atmosphere is corrosive. PBN coated graphite materials significantly enhanced the performance of the surface. Better purity, lower porosity, and roughness. PBN material could also stand high temperature (2500`C). As the coated products have great performance in high vacuum and high-temperature circumstance, they are ideal for applications in the semiconductor industry.
