マルワイ矢野製陶所 List of Products and Services

BN (boron nitride) is a ceramic with excellent lubricating properties, high thermal conductivity, thermal shock resistance, low thermal expansion, and chemical stability. It has many similarities to graphite and is also referred to as white graphite. While graphite is dielectric, BN possesses high electrical insulation properties. It is used in applications such as fixtures for glass manufacturing, crucibles for metal melting, injection nozzles, electrical insulation components, and semiconductor manufacturing components. Additionally, BN-AlN, which is blended with AlN to enhance hot strength, can also be produced.
