Product Information

Boron Nitride is a synthetic technical ceramic material, which is available in powder, solid, aerosol and liquid forms. It has out-standing thermal characteristics; high thermal conductivity and excellent thermal shock resistance and is stable in inert and reducing atmospheres up to 2000 C, and in oxidizing atmospheres to 850 C. In its solid form, Boron Nitride can easily be machined to close tolerances in virtually any shape. After machining, it is ready for use without additional heat treating or firing operations.

Boron Nitride Properties:

*Excellent thermal shock resistance

*High electrical resistivity

*Low density

*High thermal conductivity

*Isotropic (thermal conductance is different in different planes)

*Corrosion resistant

*Good chemical inertness

*High temperature material

*Excellent lubricating properties

*Low coefficient of friction

*Non-wetting (without oxidization)

*High dielectric breakdown strength

*Excellent Machinability

Typical Uses of Boron Nitride

*Electronic parts - heat sinks, substrates, coil forms, prototypes

*Boron doping wafers in silicon semiconductor processing

*Vacuum melting crucibles

*CVD crucibles

*Microcircuit packaging
