>Boron Nitride Material Properties.

Boron Nitride Grade BN100, BN200 & BN300 

Boron nitride is a unique material. it offers outstanding thermal conductivity, excellent dielectric strength, very good thermal shock resistance and is easily Machinable. This material is an advanced synthetic ceramic available in powder, solid, liquid and aerosol spray forms. In an oxidizing atmosphere it can be used up to 900C. However, in an inert atmosphere some grades can be used as high as 3000C. Grades are available with a very low porosity and ultra high strength for use in semiconductor processing applications.
