b4c We are professional for providing boron carbide ceramic solutions in shanghai in china. Boron carbide commonly known as man-made diamond, is a kind of very high hardness boride.Boron Carbide Ceramics is very light technical ceramic material (about 2.5 g/cm3) as well as the hardest (be next only to diamond).Boron carbide is more stiffer and more hard than silicon carbide or tungsten carbide Boron carbide, B4C, is one of the hardest materials in the world, ranking third behind diamond and cubic boron nitride, and it is the hardest material produced in tonnage quantities. Discovered as a byproduct in the production of metal borides during the 19th century, it is produced by reacting carbon with B2O3 in an electric arc furnace through carbo-thermal reduction or gas phase reactions. Boron carbide must be milled and purified to remove metal impurities prior to commercial use. boron carbide Boron carbide, the molecular formula B4C, usually of black powder. Commonly known as man-made diamond, is a kind of very high hardness boride. And acid, alkali solution can not react, easy to manufacture and relatively cheap price. Widely used in hard material grinding, grinding, drilling and other.Mohs hardness is 9.3. It is widely used in ballistic armor systems, Nozzles,Seal ring, Shaft sleeve, Nuclear Industry Materials,Grinding Materials,wear resistant lining and so on.Also we can make according to your requirement. boron carbide ceramic Boron carbide nozzle has the characteristics of high wear resistance and high hardness,high compressive strength, strong impact resistance,does not react with acid and alkali.Sintered by pure boron carbide powder,improves sandblasting efficiency, and sandblasting jet is stable,service life is very very long,wear resistance life of boron carbide nozzle is 5-10 times longer than that of tungsten steel.The boron carbide nozzle is gradually replacing the cemented carbide (tungsten steel) and silicon carbide, silicon nitride, alumina, zirconia and other materials. We can supply series of boron carbide ceramic nozzle for sandblasting,such as Boron carbide straight bore nozzle,straight bore nozzle with screw thread,venture nozzle with screw thread, lead-in nozzle and so on.Also we can make boron carbide nozzles according to your design.
