Hexagonal Boron Nitride Powder 50 Nano Super Fine 99% Food Grade Cosmetic Grade Cubic Boron Nitride Powder
Hexagonal Boron Nitride:White graphite is another name for hexagonal boron nitride. White graphite is the simplest boron-nitrogen polymer. Similar to the hexagonal carbon network in graphite, nitrogen and boron in hexagonal boron nitride also form hexagonal network layers that overlap each other to form crystals. The crystal is similar to graphite, with diamagnetism and high anisotropy, and the crystal parameters are also quite similar. Boron nitride is mainly used in refractory materials, semiconductor solid-phase doping sources, structural materials of atomic stacks, packaging materials against neutron radiation, rocket engine components, high-temperature lubricants and mold release agents.

Suoyi hexagonal boron nitride (hBN) powder is synthesized through a high-temperature reaction between boric acid and nitrogen at over 1900°C, resulting in an ultra-fine, slippery white powder with exceptional thermal and chemical stability.
Custom particle sizes & surface treatments available upon request.
Hexagonal boron nitride (hBN) is a premium-grade advanced ceramic material offering exceptional thermal conductivity (300-600W/m·K), outstanding electrical insulation (>1014 Ω·cm), and superior chemical resistance.
With a melting point above 3000°C, it excels in extreme environments where traditional materials fail.
Applications
* Thermal Interface Materials (TIMs) for CPUs/GPUs
* High-Temperature Lubricants & Mold Release Agents
* Polymer Composites (enhanced strength & heat dissipation)
* Cosmetic & Coatings (smooth, non-toxic additive)
