Hexagonal vs. Cubic Boron Nitride (h-BN vs. c-BN)

Hexagonal boron nitride (h-BN) and cubic boron nitride (c-BN) are two distinct forms of boron nitride with different crystal structures and properties.
h-BN (Hexagonal Boron Nitride):
● Excellent thermal stability
● Electrical insulation
● Corrosion resistance
● Lower mechanical strength compared to c-BN
● Common applications: lubricants, thermal interface materials, electronic heat dissipation
c-BN (Cubic Boron Nitride):
● Extremely hard and wear-resistant
● High temperature and chemical resistance
● Ideal for cutting tools, abrasives, and high-performance industrial components
Choose the right boron nitride type based on your application needs.

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.
