* Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.

* Hexagonal boron nitride has a layered structure similar to graphite. Within each layer, boron and nitrogen atoms are bound by strong covalent bonds, whereas the layers are held together by weak van der Waals forces.

* Unlike to grape, h-BN’s lubricity doesn’t rely on atmospheric condition which has potential application in vacuum.

H-BN-A, B, C
Medium crystallization, excellent high temperature resistance and oxidation resistance, its original particle size is small, agglomeration particle size is large. Because the particles are spherical, so it is particularly suitable for filler, mold release agent for casting and injection process. Composite ceramics, also easy to hot press into shape.

H-BN-D
Tight distribution of particle size; Because its particle size is similar to PTFE, so it is particularly suitable for
high-pressure switch nozzles: Superior thermal conductivity, it is very suitable for thermal conductive plastic or thermal
conductive rubber; Low oxygen content (generally less than 0.5%) is also particularly suitable as a material for special ceramics.

H-BN-E, H-BN-G
High crystallinity and tight distribution of particle size. Compared to other products, it is higher crystallinity and better
properties of thermal conductivity, insulation, lubrication, high temperature resistance and resistance to corrosion from molten metal. It can be used in various high-end fields, including cosmetics and thermally conductive materials. Replacement of other expensive HBN products.

H-BN-F
High thermal conductivity, electrical insulation, low dielectric constant, low expansion coefficient, and good stability, so it is often used as an additive in the electronics industry. Currently, other application areas of this product are being developed.
