Product Description 99.99% Boron nitride rod ceramic rod for Horizontal Steel CastingMaterial: Boron Nitride / PBN 99.9%Typical Applications: 1. Spectrometre2. High temperature furnace3. Crystal growth4. LEC crucible, VGF crucible, MBE crucible5. MOCVD insulation plate6. Heating element7. Microwave8. Semiconductor9. Composite HeaterBoron Nitride (BN) is a white, low porosity refractory material with physical and mechanical properties similar to Graphite. However, unlike Graphite, Boron Nitride has high thermal conductivity and good thermal shock performance. The most common formulation of Boron Nitride contains boric oxide, which can cause Boron Nitride to absorb moisture, resulting in swelling and property degradation.
