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:
Material | Description |
BN99 | Hot pressed at high temperature (1900C). Excellent corrosion resistance and thermal conductivity. Limited wear resistance Self-bonded and high purity (>99%) |
BNBO | General-purpose material Bonded by boric oxide |
BNCB | Calcium borate bonded boron nitride Enhanced moisture resistance |
BN60 | BN 60%, SiO2 40% |
BN40 | BN 40%, SiO2 60% |
ZSBN | BN-45%, Zr2O3 45% |
