Hexagonal boron nitride (h-BN), an advanced inorganic non-metallic material combining ceramic and lubricant properties, demonstrates irreplaceable application value in high-end industrial fields due to its unique layered crystal structure and outstanding physicochemical performance. Henan BN(CHINA) Technology Co., Ltd., as one of China's leading enterprises in the full industrial chain of carbon/nitroboron materials, provides the market with high-performance hexagonal boron nitride powder products through continuous technological innovation and large-scale production.
The core advantage of h-BN powder stems from its molecular structural characteristics. This material features alternating boron and nitrogen atoms forming hexagonal planar networks, with interlayer bonding via van der Waals forces. This structure confers an exceptionally low coefficient of friction and outstanding high-temperature stability. In oxidizing atmospheres, h-BN remains stable up to 850°C, while in inert environments it withstands temperatures exceeding 1370°C. Its extremely high melting point far surpasses traditional lubricants. Its chemical inertness is equally remarkable, exhibiting minimal wettability with molten metals (aluminum, magnesium, copper, etc.), glass melts, and most chemicals, effectively preventing mold adhesion and chemical corrosion. Furthermore, h-BN combines high electrical resistivity with high thermal conductivity, making it an ideal insulating and heat-dissipating material for high-temperature electronic devices.
Regarding product specifications, BN(CHINA) Technology achieves multi-dimensional parameter customization through refined process control. Particle sizes span the D50=4-20μm range, with micron-level to submicron powders available per customer requirements. The PBN700 grade achieves 99.5% purity, ensuring no impurity volatilization under high-temperature conditions. Optimized layered structure technology further enhances material performance. Powder with high aspect ratio forms a horizontally oriented thermal conduction network within coatings, significantly improving lubricity and heat transfer efficiency. For diverse application scenarios, the company offers hexagonal boron nitride powder in multiple specifications and purities. Contact us for purchasing inquiries.
