PBN1344 Pyrolytic Boron Nitride Strip (PBN Strip)

Description Pyrolytic Boron Nitride

Pyrolytic boron nitride (PBN) contains raw materials with a significantly higher purity level than traditional boron nitride ceramic. It is a high purity material characterised by the absence of porosity, which can be deposited on various graphite shapes via chemical vapour deposition (CVD). Although pyrolytic boron nitride can be deposited on different materials, it is primarily applied to graphite due to the extreme temperatures and corrosive atmosphere involved in the CVD process. PBN coated graphite materials markedly improve surface performance. Enhanced purity, reduced porosity, and surface smoothness are notable characteristics. Moreover, PBN material can withstand high temperatures (up to 2500`C). The coated products exhibit effective performance in high vacuum and elevated temperature environments, making them suitable for applications in the semiconductor sector.
