Boron Nitride

Boron Nitride Product Classification Introduction

Boron nitride (BN) is a premium functional boron-based material with an extremely versatile set of properties. BoronHub offers two core product lines: hexagonal boron nitride (h-BN) and cubic boron nitride (CBN), serving multiple high-end industries such as lubrication, thermal management and superhard precision machining.

Hexagonal Boron Nitride (h-BN)

Nicknamed "white graphite", h-BN is pure white powder that integrates excellent high-temperature lubricity, high thermal conductivity, superior electrical insulation, chemical inertness and strong neutron absorption capacity. BoronHub supplies customized flaky h-BN powder with high purity and high crystallinity, with particle sizes reducible to less than 1 μm. Its typical application scenarios include high-temperature release agents, chip thermal interface materials, aerospace wave-transparent composites, neutron shielding materials for nuclear power, and functional fillers for luxury cosmetics.

Cubic Boron Nitride (CBN)

CBN is a superhard material whose hardness is second only to diamond. Its wear resistance exceeds that of conventional abrasives by over four times, paired with outstanding thermal stability and chemical inertness, making it perfectly suited for high-precision grinding of ferrous metals and their alloys. BoronHub provides single-crystal CBN (HBCBN series, Ti hardness index: 63–76) and CBN micropowder (12 grades with D50 ranging from 1.25 μm to 32 μm) compatible with all types of binder systems. It is widely used in CBN grinding wheels, PCBN cutting tools, automotive component precision machining and heat dissipation for electronic packaging.

Supported by high purity, exceptional thermal stability, a full spectrum of particle sizes and flexible customization services, BoronHub delivers comprehensive boron nitride material solutions for global clients.
