Boron Nitride Machined Parts Advantages & Applications:
Boron Nitride ceramic from Boron Carbide Parts China Ceramics Division can withstand high temperatures in a 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 custom machined parts are an ideal choice in a wide range of industries, such as:
-Boron Nitride parts for ion injection equipment
-Electric insulators in vacuum system
-Spacers for glass melting
-Feed through for high voltage equipment
-Boron Nitride components for PVD, MOCVD, MBE system.
Packing
As a ceramic material, boron nitride is quite fragile in a lot of cases. Our Hot-Pressed Boron Nitride Crucible 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.
