Typical Applications 

General purpose 

Outstanding moisture resistance, refractory, dielectric strength 

High temperature and purity. Dielectric strength, low expansion, high thermal conductivity 

Extreme corrosion resistance, high purity temperature, thermal conductivity 

Extreme thermal conductivity, moisture resistance, dielectric strength 

Extreme thermal conductivity, moisture resistance, dielectric strength 

Extreme wear and corrosion resistance in molten metal applications

High Grade Materials

Pyrolytic Boron Nitride

PBN’s properties, its intrinsic purity, superior mechanical strength, and thermal stability make it a superb choice for high temperature furnace and electrical components; microwave and semiconductor components; and industry standardised crucibles for gallium arsenide crystal (GAN) production.

Other properties featured in our Performance PBN include: Good thermal conductivity, High insulation resistance, High dielectric strength over wide temperature ranges., Extremely pure, Non-wetting, Non-toxic, Non-reactive to most other compounds, Withstands high temperatures and rapid cooling

PBN will not react with acids, alkalis, organic solvents, molten metals, or Graphite. Bulk impurity levels are less than 100 parts per million with metallic impurities less than 10 parts per million. It withstands 1800° C in vacuum and 2000° C in nitrogen, showing no melting point, making it an excellent choice for furnace components, and melting vessels. Crucibles heated to 1200°C can be plunged into liquid nitrogen without visible damage. PBN-coated graphite heating elements provide extremely uniform temperature profiles for both compound and silicon semiconductor manufacturing.
