Boron Nitride Gasket Advantages & Applications:

 

Boron Nitride ceramic from Edgetech Industries Ceramics Division can withstand high temperature in the high vacuum environment, plus it has excellent corrosion resistance and electrical resistance.

-Low wettability to molten metal
-Relatively high thermal conductivity with low thermal expansion
-Relatively high thermal shock resistance
-Extremely high working temperature with proper inert gas protection (>3000C has been recorded).

Based on the above properties, Boron Nitride Tube is an ideal choice in a wide range of industries, such as:

-Boron Nitride components for PVD, MOCVD, MBE system.
-Insulators for high temperature furnace
-Feed through for high voltage equipment
-Spacers for glass melting
-Boron Nitride parts for ion injection equipment

 

Packing

 

As a ceramic material, boron nitride is quite fragile in a lot of cases. Our Hot-Pressed Boron Nitride Gasket is carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used for BN products, vacuum packing is also engaged for some of the parts.
