Pyrolytic Boron Nitride (PBN) Plate/Sheet/Disc

PBN1279

New product

PBN Plate/Sheet/Disc are often used as insulation parts in high vacuum and high temperature environments because of their excellent high temperature electrical insulation properties and ultra-high purity. The purity can be 99.999% with high density. It is made by ammonia and Boron halide through a Chemical Vapor deposition(CVD) process in high temperature and high vacuum conditions.
