Product Description

 

Product Description

Boron Nitride is a high-temperature ceramic that has a structure similar to graphite. Our portfolio of hot-pressed solid materials includes pure Hexagonal Boron Nitride as well as composites suitable for applications requiring excellent thermal properties combined with electrical isolation.
Easy machinability and fast availability make Boron Nitride an outstanding choice for prototypes to large quantities requiring its unique properties.
 

Typical Grades	BN997 (99.7%); BN993 (99.3%); ALBN (Al2O3-BN); SCBN (SiC-BN); ZRBN (ZrO2-BN); ANBN (AlN-BN); SNBN (Si3N4-BN)
Typical Properties	Low density Low thermal expansion Good thermal shock resistance Low dielectric constant and loss tangent Excellent machinability Chemically inert Corrosion resistant Non-wetting by most molten metals Extremely high working temperature
Typical Applications	High-temperature furnace setter plates Molten glass and metal crucibles High-temperature and high-voltage electrical insulators Fittings and the lining of the plasma chamber Nonferrous metal and alloy nozzles Thermocouple protection tubes and sheath Boron doping wafers in silicon semiconductor processing Sputtering targets Break rings for horizontal casters
