Your Trusted Boron Nitride Ceramic
Boron nitride is a crystal composed of nitrogen and boron atoms (BN), with properties such as low friction, lubrication, light weight, and moisture absorption.
Boron nitride is mainly available in hexagonal phase (h-BN), used for high-temperature and electrical insulation applications, and cubic phase (c-BN), used for cutting tools and abrasives due to its hardness second only to diamond.
Boron Nitride Products
The thermal conductivity of boron nitride ceramic is similar to metal and widely used in applications requiring efficient heat dissipation. Boron nitride ceramics resist high temperatures and can work in environments above 2000°C, with a layered structure similar to graphite that provides self-lubricating properties under high temperature and pressure.

Features of Boron Nitride Ceramic
The Difference Between Hexagonal (h-BN) and Cubic (c-BN) Boron Nitride
Hexagonal and cubic boron nitride are both BN crystal phases, but their different crystal structures give them significantly different properties.
Hexagonal boron nitride (h-BN) has lower mechanical strength but good heat and corrosion resistance, used for high-temperature and electrical insulation applications. Cubic boron nitride (c-BN) has hardness second only to diamond, making it well suited to cutting tools and abrasives.

Frequently Asked Questions
What is the difference between hexagonal and cubic boron nitride?
h-BN has a graphite-like layered structure with good heat resistance and insulation, while c-BN has a diamond-like structure with much higher hardness, suited to cutting tools and abrasives.
Is boron nitride ceramic electrically insulating?
Yes — h-BN in particular offers excellent electrical insulation combined with good thermal conductivity.
Can boron nitride withstand very high temperatures?
Yes, boron nitride maintains stability at high temperatures, with h-BN commonly used above 2000°C in inert or vacuum conditions.
Why is boron nitride considered self-lubricating?
Yes, boron nitride maintains stability at high temperatures, with h-BN commonly used above 2000°C in inert or vacuum conditions.
