Product Description

 

 

 

Boron nitride, also known as white graphite, has a structure similar to that of graphite. It has good electrical insulation,thermal conductivity, excellent thermal shock resistance, and Chemical stability. Boron nitride ceramics are processed by hot-pressing and sintering boron nitride powder into product blocks according to the customer's required size specifications.

 

HBN is much superior to Graphite and has the following characteristics:
* Excellent Lubricating Properties due to low Coefficient of Friction at 0.15 to 0.70
* Good Chemical Inertness
* Electrical Insulator
* Thermal Conductor (result: better heat dissipation)
* High Temperature Stability, 1000°C in Air, 1400°C in Vacuum and 1800°C in Inert gas
* Low Thermal Expansion
* Low Dielectric Constant
* High Load bearing properties
