PBN (Pyrolytic Boron Nitride) is an anisotropic, high temperature ceramic, which exhibits a unique combination of high electrical resistance and good thermal conductivity.
This inert, non-porous compound is exceptionally pure by virtue of its synthesis process (high temperature/low pressure chemical vapour deposition).
We can supply at very competitive prices. PBN crucibles are not stocked items, delivery is usually 14 to 30 days. We have a minimum order number of 4 items of any single size.
