Your Trusted Boron Nitride Ceramic

Boron nitride is a crystal composed of nitrogen and boron atoms, with a molecular formula of BN and a molecular weight of 24.81. The chemical composition is 43.6% boron, 56.4% nitrogen, and the theoretical density is 2.27 g/cm³. Boron nitride powder features include loose packing, lubricity, light weight, moisture resistance, and a white color. BN products are ivory white. At present, boron nitride mainly exists in its hexagonal phase (H-BN) and cubic phase (C-BN). The primary applications of C-BN are: cutting tools, abrasives, and finishing materials, suitable for cutting all metals and non-metals, including ferrous metals, and for final finishing. The structure and properties of H-BN are similar to graphite, making it an excellent high-temperature lubricating material and high-temperature electrical insulator. Therefore, because of its different crystal structures, boron nitride can be used in various situations and can be formed into diverse ceramics.

The difference between hexagonal boron nitride(h-BN) and cubic boron nitride(c-BN)

Hexagonal boron nitride(h-BN) and cubic boron nitride(c-BN) are both boron nitride, but due to different crystal structures and properties, their applications are very different.

The mechanical strength of hexagonal phase boron nitride is lower than that of cubic phase boron nitride, but both have good heat resistance and corrosion resistance.

Our most frequently asked questions

What is the difference in thermal conductivity between boron nitride ceramics and other common insulating ceramics?

Answer:
Boron nitride ceramics typically exhibit higher thermal conductivity than most common insulating ceramics while still maintaining excellent electrical insulation and chemical stability, making them standout in applications requiring fast heat dissipation with insulation.

Why is boron nitride ceramic considered an ideal thermal-management insulation material?

Answer:
Because it combines high thermal conductivity, low thermal expansion, excellent electrical insulation, and good chemical stability, making it suitable for thermal management in electronics, optoelectronics, and high-temperature environments.

What is the thermal shock stability of boron nitride ceramics?

Answer:
The melting point of boron nitride ceramic is very high, reaching more than 3,000°C, and it has excellent thermal shock stability and will not produce cracks even if the temperature changes drastically. The relatively low thermal expansion coefficient ensures that the volume does not change greatly during the heating process. At the same time, boron nitride ceramics are very good at resisting oxidation corrosion at high temperatures due to the adhesion of the oxide film. These characteristics make it an ideal choice for many high-temperature applications.
