Boron Nitride Properties

Boron nitride has high heat capacity, outstanding thermal conductivity, easy machinability, lubricity, low dielectric constant, and superior dielectric strength.

To make solid shapes, hBN powders and binders are hot-pressed in billets up to 490mm x 490mm x 410mm at pressures up to 2000 psi and temperatures up to 2000°C. This process forms a material that is dense and easily machined and ready to use. It is available in virtually any custom shape that can be machined and has unique characteristics and physical properties which make it valuable for solving tough problems in a wide range of industrial applications.


Excellent thermal shock resistance

High electrical resistivity – excluding aerosols, paints, and ZSBN

Low density

High thermal conductivity

Anisotropic (thermal conductance is different in different planes relative to pressing direction)

Corrosion resistant

Good chemical inertness

High temperature material

Non-wetting

High dielectric breakdown strength, >40 KV/mm

Low dielectric constant, k=4

Excellent machinability

Some of the most common boron nitride applications we complete include:


Furnace fixture supports and components

Melting crucibles for glass and metals

Plasma and welding tip insulators

High temp thermal complete systems

Molten metal carrier pipes

Nuclear reactor shields and linings

Semiconductor wafers

Ceramic bushings
