Our Technical Ceramics offer high-temperature material solutions for extreme environments. Contact us to find out more about Ceramics and Graphite ranges.
Thermic Edge offers Boron Nitride, a material used for high temperature applications with excellent thermal conductivity, high electrical resistance, and low thermal expansion. Depending on the required application, they are used as precision components, coatings, powders, and lubricant additives in several different high-temperature applications and numerous industries: Semiconductor, LED, Photovoltaic, Vacuum Furnaces, Atomising, and Horizontal Casting. PVD, Plasma Systems, Sintering and Powder metallurgy, Lubricant and Aluminium Casting.
Thermic Edge does not just offer Boron Nitride and composites but also Mykroy, Alumina Silicate, Macor Alumina, Silicon Nitride, Zirconia, and Aluminium Nitride.
PBN is a ceramic made by a chemical vapour deposition process which gives this material a very unique character. Intrinsically pure, it’s the ideal choice for furnace, electrical components, microwave and Semiconductor applications.
Industry standard crucibles such as VGF, LEC, Bridgman for Gallium Arsenide crystal production and auxiliary effusion cell hardware. PBN/PG Heaters can also be manufactured to provide extremely uniform temperature profiles for both compound and semiconductor manufacturing. With bulk impurities at less than 100 parts per million and metallic impurities less than 10 parts per million, PBN will not react with acids, alkalis, organic solvents, molten metals and graphite’s.

BN can be offered in many forms including Powder, Paint, Paste, Aerosol and in Hot pressed solid form.
Hot pressed boron nitride has a hexagonal structure like that of graphite. Although HPBN is an insulator with outstanding properties in Temperature, Dielectric constant, Thermal shock, Thermal conductivity. It can also be easily machined into intricate shapes with no post firing necessary. Hot pressed boron nitride is a powder which is sintered at 2000 deg C plus. Depending on the process there are several grades that can be selected for your requirement. Whether its extreme high temperature high vacuum using no binder due to thermal extraction to moisture resistance using calcium borate glass as a binder. There is a grade of HPBN for most applications.
By changing the Boron Nitride properties adding zirconia for molten metal applications such as break rings for horizontal casting or Silica for unparallel resistance to thermal shock and resistance to moisture and Aluminium nitride for excellent thermal properties it can enhance the properties of Boron Nitride.
