details of boron carbide powder w28

  Boron carbide powder is an ash black powder, also called tetra-boron carbide. The molecular formula of it is B4C. Because boron carbide powder is a kind of high hardness boride, it is commonly called artificial diamond. It can not react with acids/ caustic solution, it is easy to produce and has reasonable price. It is widely used in cemented carbide materials grinding, milling and drilling etc.

  Boron Carbide, is the hardest of the conventional abrasives, Its Mohs hardness is 9.6, melting point 2450°C,density 2.52g/cm3. It has following unique features: neutron absorbing,of semi-conductivity, low thermal conductivity,high grinding efficiency and no reaction with either acids or alkali etc. Boron carbide is widely used to grind and polish hard metal alloy, super-hard metal, high carbide steel, jewel, hard ceramic and other hard materials, to manufacture wear-resisting parts, metal cutting tools, nozzles and neutron-absorbing rods, used as metal additive for compound materials for military planes and as raw materials for matal boride, metal ceramic, boron steel, boron alloy and for special welding and refractory materials.

FEATURES of boron carbide powder w28

1. Low density (its theoretical density is only 2.52g/cm3)

2.High hardness(Mohs hardness 9.36)
