Characters1.Extreme hardness Moh's hardness 9.36 2.Difficult to sinter to high relative density without the use of sintering aids 3.Good chemical resistance 4.Good nuclear properties 5.High temperature low density resistance gravity 2.52g/cm3 smelting point 2450°C For its good properties and characters it has wide applicationDue 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 etcTo 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 etcTo be used as raw material for ballistic armour and relative productsDue 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 neutronOther 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
