PBN/PG Composite Heating electronic Elements
Descrição dos produtos
Elementos eletrônicos de aquecimento composto PBN PG:
Pyrolytic Boron Nitride is used as the substrate for the PBN heating element. Grafite Pirolítico(PG) is placed on the surface of PBN plates by the CVD method as a conductor and heater. Depending on the different requirements of applications, the PG heating element could be covered by PBN again or just stay open.

Elementos eletrônicos de aquecimento composto PBN PG
As both PG and PBN are extremely pure (99.99% or even higher) and very stable in a vacuum or inert atmosphere, the PBN/PG Composite Heating Elements could be very durable and keep the chamber clean. It could be heated to 1600℃ in a very short time without the emission of any gas component. It also has good resistance to acid and alkali. These heating elements are ideal products for the semiconductor industry and applications that require high temperature, high vacuum, and high purity.
