Hexagonal boron nitride (h-BN), as an inorganic non-metallic material with a hexagonal lattice structure, has gained widespread attention in recent years in a number of fields due to its excellent properties. As a leading producer of hexagonal boron nitride powders,BN(CHINA) Technology's products are particularly outstanding in terms of thermal conductivity.
The excellent thermal conductivity of hexagonal boron nitride powder is mainly due to its unique crystal structure and low density characteristics. In terms of molecular structure, hexagonal boron nitride, similar to graphite, has a perpendicular anisotropy along the basal plane, a structure that allows it to have extremely high thermal conductivity in the parallel direction. Specifically, the thermal conductivity of hexagonal boron nitride can be as high as 55 W/(m-K) in the direction parallel to the heat source and 1.3 W/(m-K) in the perpendicular direction. This property makes hexagonal boron nitride excellent in applications requiring efficient heat dissipation in the horizontal direction, such as efficient heat dissipation materials for electronic devices.
With its low density, hexagonal boron nitride powder can significantly reduce the weight of components such as chip packages, batteries, and heat sinks, thereby directly reducing the overall weight of the product. Especially in the current trend of pursuing lightweight electric vehicles, the use of hexagonal boron nitride powder not only helps to reduce the weight of the vehicle, but also effectively improve the range.
BN(CHINA) Technology synthesizes hexagonal boron nitride powder through advanced continuous calcination equipment, with stable product performance, strong batch supply capability and outstanding cost advantage. Its hexagonal boron nitride powder has high purity, low boron oxide content and appropriate crystalline particle size, which ensure the excellent thermal conductivity of the product. In addition, BN(CHINA) Technology is committed to enhancing the performance of hexagonal boron nitride powders in composites through surface modification techniques, such as non-covalent and covalent bonding modifications to improve dispersion and compatibility in organic solvents and polymer matrices. BN(CHINA) Technology hexagonal boron nitride powders are now available in four sizes for you to choose from: PBN700 (purity ≥99.5%), PBN500 (purity >99%), PBN300 (purity >98%), and PBN100 (purity >97%), with the crystalline size of the four products in the range of 1-5 μm, and the powder size of D50 between 4 μm-20 μm are all available.
Hexagonal boron nitride powder has a broad application prospect. In the field of electronic packaging, hexagonal boron nitride powder can be used to prepare low-viscosity thermally conductive potting compound to meet the heat dissipation needs of electronic equipment. In terms of thermally conductive interface materials, hexagonal boron nitride powder is widely used in semiconductors, LEDs and other fields, which can effectively reduce thermal resistance and improve device performance. In addition, hexagonal boron nitride powder can also be used for the manufacture of high-temperature antioxidant coatings, catalytic materials, etc., showing its potential value in many fields.
