Boron Nitride machinable ceramics are with unique properties – from high heat capacity and outstanding thermal conductivity to easy machinability, lubricity, low dielectric constant, and superior dielectric strength – making boron nitride a truly outstanding material. BN Ring is available from high-temperature-(1900C)-formed 99% pure composite boron nitride materials.
Thermal conductivity at 20℃
MAX-Temperature of use
Boron nitride ring has been widely used in the horizontal continuous casting separation ring of molten steel. Boron Nitride(BN), Hexagonal boron nitride (H-BN), and hot-pressed boron nitride are good self-lubricated ceramics that can withstand high temperatures and maintain their lubricating capability in a high vacuum environment. Hexagonal boron nitride (H-BN) behaves similarly to graphite mechanically but offers excellent electrical resistance.
Boron Nitride ceramics from Heeger Materials can bear 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 variety of industries, such as:
Hot pressed at high temperature (1900C).
Excellent corrosion resistance and thermal conductivity. Limited wear resistance
Self-bonded and high purity (>99%)
Bonded by boric oxide
