Hot Pressed Boron Nitride Ring Description

Boron nitride, also known as BN, Hexagonal boron nitride (H-BN), and hot-pressed boron nitride, is a good self-lubricating ceramic that can withstand high temperatures and maintain its lubricating capability in a high vacuum environment. Our Boron Nitride crucibles are made from a hot-pressed boron nitride blank. Hexagonal boron nitride (H-BN) behaves similarly to graphite mechanically but offers excellent electrical resistance.

Hot Pressed Boron Nitride Ring Advantages

- Low wetability 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).

Hot Pressed Boron Nitride Ring Applications

Boron Nitride ceramics from Advanced Ceramic Materials can withstand high temperatures in a high vacuum environment, plus it has excellent corrosion resistance and electrical resistance. Thus, Boron Nitride ceramic product is an ideal choice in a wide range of industries, such as:
- Used in nozzles for the nonferrous metals metallurgy industry
- Used in insulators for high-temperature furnaces
- Used as break rings for a horizontal casting machine
- Used to feed through for high-voltage equipment
- Used in Boron Nitride parts for ion injection equipment
