GE Advanced Ceramics Boralloy® Pyrolytic Boron Nitride (PBN)
Subcategory: Nitride
Material Notes:
Boralloy® 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 vapor deposition). It can be deposited or easily machined into a limitless number of shapes, including: crucibles, tubes, machined plate products, boats, and bottles. PBN's directional thermal conductivity provides excellent "heat spreading" capability for improved temperature uniformity. The combination of high strength, good thermal conductivity, and a low coefficient of thermal expansion make the material extremely resistant to thermal shock. PBN has found wide acceptance in the semiconductor, electronics, metallurgical, thin film, and pharmaceutical industries. Information provided by GE Advanced Ceramics.
