Pyrolytic Boron Nitride (PBN) Plates
New product
Pyrolytic Boron Nitride (PBN) is a kind of advanced ceramic, that can be produced with 99.999% purity in high density. It is made by ammonia and Boron halide through a Chemical Vapor deposition(CVD) process in high temperature and high vacuum conditions: NH3 +BX3=BN+3HX, it can be produced as PBN plates, and also can be produced as PBN final products directly like a crucible, boat, coating, etc.
