HBN powder (hexagonal boron nitride)

Hebei Suoyi New Materials Technology Co., Ltd. produces boron nitride powder. HBN powder (hexagonal boron nitride) is a layered crystalline material composed of boron and nitrogen atoms. Because its structure is similar to graphene and it is white, it is called "white graphene".

1. Production capacity and technology: The annual production capacity reaches 800 tons of hexagonal boron nitride powder. It adopts high-temperature method and continuous calcination synthesis process. The product has high crystallinity and large specific surface area, which is comparable to international quality. It adopts 3000℃ high-temperature synthesis process, 99%min ultra-high purity boron and boron nitride powder, and thermal conductivity of 250-300W/m·K. It has both high-temperature and low-temperature firing technology, and has significant environmental advantages. It focuses on the special ceramics market, and its products have the advantages of high whiteness and low oxygen content. It is used in coatings, ceramic parts, cosmetics, and lubricants.
2. Cubic boron nitride abrasive HBN, spherical BN.
- Ultra-high thermal conductivity: The room temperature thermal conductivity of single crystal is 730-751 W/m·K, which is twice that of copper, and it is an electrical insulator (thermal conductivity and insulation coexist).
- Extreme temperature resistance: Stable to 2800℃ in inert atmosphere, anti-oxidation to 1200℃ in air, and excellent thermal shock resistance.
- Chemical inertness: acid and alkali corrosion resistance, low friction coefficient (Mohs hardness is only 2), and self-lubricating.
- Lightweight and low density: Theoretical density is 2.27-2.29 g/cm³, suitable for lightweight applications.
3. R&D strength: 800 tons/year, more than 200 employees, more than 100 patents, and ISO9000 certification.
4. Deeply processed products: hot pressed ceramic parts, PBN crucibles (99.99% purity), titanium diboride composite ceramics, etc.
5. Product application: Powder and nitride ceramic products are used in aerospace, electronics, nuclear industry and other fields, with leading technical indicators in China.
