The PBN/PG ceramic heater combines three layers of ultra-high purity ceramics, PBN-PG-PBN. the PBN acts as the insulating substrate and the PG acts as the resistive element. Our PBN heaters (pyrolytic boron nitride) and PG heaters (pyrolytic graphite) are manufactured by high-temperature CVD. These high-performance elements exhibit excellent thermal properties in ceramic heaters, including high thermal conductivity and anisotropy.
Hexagonal Boron Nitride has a microstructure similar to that of Graphite. In both materials, this structure, made up of layers of tiny platelets, is responsible for excellent machinability and low-friction properties. we called hexagonal boron nitride (HBN) or white graphite.
Hot pressed BN is compacted at temperatures up to 2000°C and pressures up to 2000 psi to form a dense, strong engineering material that is easily machined. It is available in standard and custom hot pressed shapes and has several unique characteristics and physical properties which make it valuable for solving tough problems in a wide range of industrial applications.
