Boron carbide

Cas: 12069-32-8

Technical Parameters

Product Features

High purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density. It is a synthetic superhard material, second only to diamond in hardness, with stable physical and chemical properties.

Potential Application Areas:

1. Nano boron carbide powder also has higher neutron absorption efficiency than micron-grade boron carbide powder, thus widely used in nuclear and defense industries;

2. Boron carbide bulletproof armor sintered with nano boron carbide powder significantly improves mechanical properties, penetration resistance, and armor protection capabilities;

3. Nano boron carbide powder is not only used in refractory materials and precision measuring components but also in the manufacture of high-precision nozzles, sealing rings, and other fine engineering ceramic products;

4. Nano boron carbide powder is a synthetic superhard material. As an abrasive, it offers extremely high grinding efficiency without introducing impurities, making it an ideal substitute for diamond abrasives;

5. High-end refractory materials, fine engineering ceramics, such as high-precision nozzles, sealing rings, nuclear industry, and defense industry.

Packaging and Storage

This product is packaged in inert gas anti-static packaging and should be stored sealed in a dry, cool environment. It should not be exposed to air for extended periods to prevent moisture-induced agglomeration, which may affect dispersion performance and usage effectiveness.

Product Number:B-B4C-1

Performance Indicators

This product features high purity, small particle size, uniform distribution, large specific surface area, high surface activity, and low bulk density. It is a synthetic superhard material, one of the hardest artificial abrasives, with stable physical and chemical properties, non-magnetic, resistant to high and low temperatures, strong acids, and strong alkalis. Its hardness is second only to diamond. As an abrasive, it offers extremely high grinding efficiency, making it an ideal substitute for diamond. Additionally, boron carbide effectively absorbs neutrons without emitting harmful gamma rays, avoiding secondary radiation pollution.

Main Applications

Refractory Materials: B4C powder is used in carbon-containing refractories for oxidation resistance, densifying the product, preventing carbon oxidation in carbon-containing refractories, reducing porosity, improving medium-temperature strength, and reducing cracks.

Nuclear Industry: This product offers higher neutron absorption efficiency than micron-grade powder, making it widely used in nuclear and defense industries. Using B4C material as isolation blocks, storage pools originally designed for 15 years now meet the International Atomic Energy Agency's recommendation of at least 50 years of design life for temporary spent fuel storage.

Bulletproof armor with added nano B4C features high hardness and low specific gravity; mechanical properties and penetration resistance are significantly improved, making armor protection more outstanding.

High-Precision Nozzles: Due to its low specific gravity and high hardness, nano B4C is widely used in handheld sandblasting machine nozzles, water jet cutting nozzles, etc. B4C ceramic nozzles offer long service life and minimal dimensional changes.

Abrasives and Grinding Tools: Nano B4C powder is a synthetic superhard material. As an abrasive, it provides extremely high grinding efficiency without introducing impurities, making it an ideal substitute for diamond abrasives.

Grinding Media: Grinding balls prepared from nano B4C via isostatic pressing have hardness second only to diamond, making them suitable for almost all grinding applications except diamond.

Sealing Rings: Sealing rings made from nano B4C ceramics, due to their high hardness and corrosion resistance, are widely used in pumps handling liquids with high solid particle content. Their service life can exceed one year, making them ideal for sealing in extremely strict leak-free applications.
