Boron Nitride ceramic from 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 Ring is an ideal choice in a wide range of industries, such as:
-Used in nozzles for nonferrous metals metallurgy industry
-Used as break rings for horizontal casting machine
-Used in insulators for high temperature furnace
-Used to feed through for high voltage equipment
-Used in Boron Nitride parts for ion injection equipment
As a ceramic material, boron nitride is quite fragile in a lot of cases. Our Hot-Pressed Boron Nitride Ring 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.
