Pyrolytic boron nitride belongs to special ceramic materials. The deposition process of pyrolytic boron nitride is like "falling snow". The hexagonal small snow flakes of boron nitride fall on the base material one by one in parallel. After reaching a certain thickness, they are finally cooled and demoulded.High temperature resistance, and the strength increases with the increase of temperature, reaching the extreme value at 2200°C,Good thermal shock resistance, good thermal conductivity, low thermal expansion coefficient,High resistance, high dielectric strength, small dielectric constant, low magnetic loss tangent, and good microwave and infrared permeability.
PBN is made of a ceramic material called pyrolytic boron nitride. PBN crucibles have high mechanical strength and high purity,high temperature resistance,PBN crucibles have high mechanical strength and high purity.

Main properties of PBN ceramic
1. High purity (>99.99%)
2. High density (>2.12g/cm3)
3. No gas is released at high temperature
4. Uniform thickness, good heating consistency
5. Excellent thermal conductivity and thermal shock resistance
6. High interlayer strength, easy to clean and repeated use
7. Chemically inert, does not react with acids, alkalis, salts and organic solvents at high temperatures
Typical applications of PBN ceramic
1.Crucibles for in-situ synthesis of GaAs, InP, GaP and other semiconductor single crystals.
2. Crucibles and boats for the synthesis of single crystals or polycrystals of other III-V compounds.
3. MBE crucible for molecular beam epitaxy.
4. PBN/PG composite heater coating for annealing furnace.
5. Insulation parts in high temperature vacuum furnace.
6. Graphite heater insulation coating.
7. High temperature insulated nozzle.
8. MOCVD insulation board.
9. Special-shaped crucible and special-shaped graphite parts coating.
10. Crucible for special metallurgy
