Pyrolytic Boron Nitride Shapes and Coatings

High-performance, high-temperature and ultra-pure

Pyrolytic Boron Nitride (pBN), with a combination of high electrical resistance and thermal conductivity, is an excellent candidate to consider for applications where superior strength, low coefficient of thermal expansion and thermal shock resistance are required. Nonhazardous, nonporous and exceptionally pure, pBN can be applied as a coating on graphite or deposited and then easily machined into 2D or 3D shapes for use as crucibles, boats, plates, wafers, tubes and bottles. Known for its directional thermal conductivity and ability to provide optimal heat spreading, pBN demonstrates improved temperature stability up to 1700°C, is resistant to thermal shock and when coated on graphite can protect against corrosive atmospheres including most molten metals (Al, Ag, Cu, Ga, Ge, Sn, etc.), acids and hot ammonia environments.
