PBN Heater Description

High-purity and high-performance Pyrolytic Boron Nitride (PBN) ceramics serve as the substrate for PBN heaters. In these heaters, a layer of Pyrolytic Graphite (PG) is applied to the surface of PBN plates via the Chemical Vapor Deposition (CVD) method, functioning as both a conductor and heating element. Depending on application requirements, the PG heating element can either be left exposed or covered with an additional layer of PBN.

Both PG and PBN boast exceptional purity levels (99.99% or higher) and are highly stable in vacuum or inert atmospheres. This makes the PBN-PG heating element extremely durable and capable of maintaining a clean chamber environment. These heaters can rapidly reach ultra-high temperatures of up to 1600°C without emitting any gas components, making them ideal for use in the semiconductor industry and other applications demanding high temperature, high vacuum, and high purity.
