Boron Carbide is one of the hardest materials known, ranking second behind diamond. Boron carbide is characterized as following,

Extreme hardness,hardness 9.36.Difficult to sinter to high relative density without the use of sintering aids.Good chemical resistance.Good nuclear properties.

High temperature,low density,resistance gravity,2.52g/cm3, smelting point, 2450Centigrade.

For its good properties and characters,it has wide application

Due to its extreme hardness, it has good wear and abrasive resistance, then it can be used as not only lapping and polishing material, such as the polishing of high speed steel, but also cutting tools for hard metal; wire drawing dies, abrasive tools with high abrasive and wear resistance, sealed washer (gasket), and the nozzles for water jet cutters, slurry pumping, grit blashing, etc.

 To take place of diamond in the processing of semiprecious gems such as ruby, synthetic corundum etc.

 As the raw material for refractory industry, special welding, etc.

 To be used as raw material for ballistic armour and relative products.

 Due to its capability to generate tremendous amount of heat in combination with oxygen, boron carbide is used as rocket propellant in aerospace industry.

 It is widely used in nuclear industry for its good absorption of neutron.

Other using: an indispensable material for making boric metal, for example, titanium boride, boric steel, etc, the models and dies of ceramic tools, evaporating boat and parts of precision tools, etc.
