Boron carbide is one of the hardest materials available in commercial shapes, and gives outstanding resistance to abrasive wear. It has a low density but a high elastic modulus and high compressive strength. B4C can be polished to a mirror finish and has good resistance to acids, but not to alkali hydroxide melts. It is refractory and chemically inert, but less resistant to oxidation than silicon carbide..
We can supply boroncarbide ceramics in shapes of crucible, tube, rod, plate, disc, wafer, ring, nozzle, ball and so on.
