Hexagonal Boron Nitride Ceramic

Boron nitride ceramic products are made of hexagonal boron nitride powder by high temperature vacuum hot pressing sintering.

Description

Boron nitride crystals belong to the hexagonal crystal system, the structure is similar to graphite, there are many similarities in performance, so it is also called "white graphite".
It has good heat resistance, thermal stability, thermal conductivity, high-temperature dielectric strength, is the ideal heat dissipation materials and high-temperature insulation materials. Boron nitride has good chemical stability, and can resist most of the molten metal corrosion. It also has good self-lubrication.

Our boron nitride ceramics:

  • Adopt international advanced process high temperature boron nitride raw material to ensure material purity and high temperature resistance.

  • Cold isostatic pressing molding and bidirectional pressure hot pressing sintering process, high material density, long service life.

  • Stable and mature production technology and process, without adding any binder, to ensure the stability of materials.
