Boron Nitride Blank BN-AN

Boron Nitride Blank BN-AN is a type of boron nitride material with a polycrystalline structure that is composed of hexagonal boron nitride particles that are fused together. BN-AN is a high-purity, high-strength material that exhibits excellent thermal and electrical insulation properties, high thermal stability, and resistance to thermal shock and chemical attack.

BN-AN can be manufactured using a hot pressing method where hexagonal boron nitride powder is compacted into the desired shape and then heated at high temperatures and pressures to create a dense, polycrystalline structure. The resulting material has a high degree of homogeneity and consistent properties throughout.

BN-AN has many potential applications in high-tech industries, including electronics, aerospace, and energy. In electronics, it can be used as a heat sink material and as a high-temperature insulator. In aerospace, it can be used as a thermal barrier coating for engine components and as a material for rocket nozzles. In energy, it can be used as a filler material in high-temperature composite materials for nuclear reactors and solar cells.

Boron Nitride Blank BN-AN composites by a novel process referred to as transient plastic phase processing (TPPP). The relative density of hot-pressed composites decreased with increasing BN content, but over 99% could be obtained with 30% BN in AlN.BN-AlN gears offer a reliable driving performance under high temperature gas atmospheres in which quartz etc. cannot be used.


● Higher hardness and good wear resistance.

● High mechanical strength and thermal conductivity.

● Used as gears offer a reliable driving performance etc.


● Insulator.

● Component for semiconductor equipment.

● Jig material for molding glass.

● Bearing and cogwheel.
