Boron nitride is offered in several grades each with unique materal properties. All however, are readily machinable; much like green (not sintered), alumina BN allows drilling, tapping, treads etc. without the need for diamond tools.Features:
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
Processing of Boron Nitride Ceramics:
Hot Pressed Sintering
Chemical Vapor Deposition
Boron Nitride applications include microwave components, electronic parts, semiconductor, prototypes, high temperature furnace fixtures, and supports, etc.
