The PBN/BN Crucibles is widely used For Semiconductor, Electronics, Metallurgical, Thin Film, and Pharmaceutical Industries.

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.

Generally  We don't have any stock crucibles. The maximum size of our PBN crucibles we can produce is OD330x500mm with 1mm wall thickness. Produce times are generally 4-6 weeks after receive the payment. All pyrolytic boron nitride crucibles are fully cleaned before packaging and shipping.
