boron carbide nanopowder,
high temperature castable refractory
Boron Carbide is the lightest technical ceramic material (2.5 g/cm³) as well as the hardest (second only to diamond).
Boron Carbide Powder is mainly produced by reacting carbon with B2O3 in an electric arc furnace, through carbo thermal reduction or by gas phase reactions. For commercial use, B4C powders usually need to be milled and purified to remove metallic impurities.
Boron Carbide powder is one of the most hardness materials in the world. Its Mohs hardness is 9.3. B4C is with the properties of low density, high strength, high temperature stability and chemical stability characteristics. B4C is mainly used in wear-resistant materials, ceramics reinforced and grinding,
Physical And Chemical Properties

1. B4C is with high hardness abrasives can be used for all kinds of hard metal, corundum or glass processing, also to produce wear and corrosion resistance boron carbide devices. Topical boron carbide material may also be used as a cutting blade, mortar and pestle and the like.
2. Can be used as raw material in the chemical or other alloy steel boron agents, generates diboride iron to reinforce the strength and wear resistance of material, it can also be used in some metallic friction material additives. B4C can be produced TiB2, ZrB2, CrB2 and other powders.
3. It can be made of boron carbide conductive properties of boron carbide - graphite thermocouple.
4. The use of nuclear energy in the neutron absorbing ability of the advantages of neutron absorbing material is used as control rod adjustment bar, rod accident, safety bars, rods and other features of the original shield.
5. By adding a sintering additive to improve the performance of boron carbide ceramic composites, access to quality and low price boron carbide products. Boron Carbide powder now is widely used in the industrial of nozzles, pump seals and hot extrusion die fields.
