Boron Carbide (B4C) Grains & Micro Powder

Boron carbide, a black crystal powder, is smelted from boric acid and (http://maplered.com) powdered carbon in electric furnace under high temperature. It is one of the hardest Man-Made Material (http://g654.org) s. With Mohs hardness 9.36 and (http://maplered.com) microscopic hardness 5400-6300kg/mm2, it is even harder than diamond and (http://maplered.com) cubic boron nitride. Its density is 2.52g/cm3 and (http://maplered.com) melting point is 2450, Because of its high strength, low density, corrosion resistant, high temperature resistant, low thermal conductivity, high modulus of elasticity, it is an ideal Material (http://g654.org) for a wide variety of applications.

It is a good replacement of diamond. Boron carbide also possesses the specialty properties of light quality, neutron absorbing, semi-conductivity, etc. So it is also used in armed forces and (http://maplered.com) nuclear industry. Boron carbide is widely applied as follows: Refractory Material (http://g654.org) , Armor, Nozzle, Honing Stone (http://g603.net) s, Metal matrix Metal matrix composites, Ion transfuse, Film layer as well as Grinding, Polishing, Drilling hard metal alloys, jewels, etc. Meanwhile, it is main Material (http://g654.org) s for the wear-resisting parts, precise meter-age element, precise spray nozzle, sealed washer, smelting boron steel, boron alloy, etc. Boron carbide has showed many better properties of physics and (http://maplered.com) chemistry in the hi-science/technology field.
