1. Boron nitride
is a white solid material in the as 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.
BN is made using a hot pressing process, and comes as a lubricious white solid. It can be machined using standard carbide drills. Due to crystal stucture, BN is anisotropic electrically and mechanically. BN exhibits a high electrical resistance, low dielectric constant and loss tangent, low thermal expansion, chemical inertness, and good thermal shock resistance.
There are several different purity levels for this material. All offer very high thermal conductivity and stability in inert and reducing atmospheres up to ***0°C, and in **0°C in oxidizing environments. Typical uses include vacuum components, low friction seals, various electronic parts, nuclear applications, and plasma arc insulators.
