product Description

Boron nitride crystal belongs to the hexagonal crystal system, has similar structure to graphite, and has many similarities in properties, so it is also called "white graphite".

product features

  • Heat resistance, thermal stability, thermal conductivity, high-temperature dielectric strength, is an ideal heat dissipation material and high-temperature insulation material
  • Boron nitride has good chemical stability and can resist the erosion of most molten metals
  • thermal shock resistance

product features

  • The boron nitride sheath maintains structural and performance stability in high temperature environments, can withstand high thermal shocks and thermal expansion and has high thermal conductivity, and is both a good conductor of heat and a typical electrical insulator.
  • From the perspective of energy consumption reduction, the power of other products can be reduced by 3-5KW
