Description

Boron nitride is a white solid material, it was produced hot pressed form. It is a low porosity solid. It is easily machined into complex shapes using standard carbide tooling. The material is anisotropic in its electrical and mechanical properties due to the platy hexagonal crystals and their orientation during the hot press consolidation. Key Properties High thermal conductivity Low thermal expansion Good thermal shock resistance High electrical resistance Low dielectric constant and loss tangent Microwave transparency Non toxic Easily machined — non abrasive and lubricious Chemically inert Not wet by most molten metals Typical Uses Electronic parts — heat sinks, substrates, coil forms, prototypes Boron doping wafers in silicon semiconductor processing Vacuum melting crucibles CVD crucibles Microcircuit packaging Sputtering targets High precision sealing, brazing, and metallizing fixtures Microwave tubes Horizontal caster break rings Low friction seals Plasma arc insulators High temperature furnace fixtures and supports
