Pyrolytic Boron Nitride (PBN)

Pyrolytic Boron Nitride (PBN) is an anisotropic, high-temperature ceramic which exhibits a unique combination of high electrical resistance and good thermal conductivity.

This non-toxic, non-porous compound is exceptionally pure by virtue of the synthesis process (high temperature/low pressure chemical vapour deposition).

It can be deposited or easily machined into a limitless number of components.

PBN’s directional thermal conductivity provides excellent ‘heat spreading’ capability for improved temperature uniformity.

With its high strength, good thermal conductivity, and a low coefficient of thermal expansion this makes the material extremely resistant to thermal shock.

PBN has found wide acceptance in the semiconductor, electronics, metallurgical, thin film, and pharmaceutical industries.
