Boron Nitride (BN)
Boron Nitride, is an advanced ceramic material synthesized from hexagonal boron nitride. Known as "white graphite" . Boron nitride resembles graphite, but unlike graphite, it acts as an excellent electrical insulator with
a higher oxidation temperature. It exhibits remarkable thermal conductivity, thermal shock resistance, and can be easily machined into precise shapes.
The performance and suitability of Boron Nitride materials are influenced by variations in their composition, including the type and amount of binder, overall composition, and the bonding between layers. These factors play a crucial role in determining the unique characteristics exhibited by different Boron Nitride products. With the backing of industry-leading international technical support from MASCERA offers a comprehensive range of solutions, including machinable blanks and customized finished shapes.

Data Sheet
Processing
Hot Pressed Sintering（HPBN）
Hot Pressed Boron Nitride (HPBN) is produced through hot-pressing sintering. It offers high density, strength, and cost-effectiveness. HPBN exhibits excellent electrical insulation, lubricity, high-temperature stability, thermal conductivity, dielectric strength, and processability. It finds applications in crucibles, liquid metal conveying pipes, rocket nozzles, high-power device bases, steel casting molds, and insulating materials.
Chemical Vapor Deposition（PBN）
Pyrolytic Boron Nitride (PBN) is synthesized using chemical vapor deposition (CVD) under high temperature and high vacuum conditions. It has high purity, thermal conductivity, mechanical strength, electrical insulation, chemical inertness, and non-toxicity. PBN is used as a container material for element purification and semiconductor crystal growth. Applications include OLED evaporation units, semiconductor single crystal growth crucibles, molecular beam epitaxy (MBE) evaporation crucibles, MOCVD heaters, and high-temperature, high-vacuum equipment insulation boards.
Applications
Thermal Management
Excellent electrical insulation and thermal conductivity make BN very useful as a heat sink in high-power electronic applications. Its properties compare favorably with beryllium oxide, aluminum oxide, and other electronic packaging materials, and are easier machinable to desired shapes and sizes.
High Temperature Environments
Temperature stability and excellent resistance to thermal shock make BN the ideal material in the toughest high-temperature environments such as equipment for plasma arc welding, diffusion source wafers, and semiconductor crystal growth equipment & processing.
Molten Metal Handling
BN is inorganic, inert, nonreactive with halide salts and reagents, and is not wet by most molten metals and slags. These characteristics, combined with low thermal expansion, make it ideal for interface materials used in various molten metal processes.
