>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 900°C. However, in
an inert atmosphere some grades can be used as high as 3000°C. Grades are
available with a very low porosity and ultra high strength for use in
semiconductor processing applications.
