Black Sic Grain Black Silicon Carbide Grit for Smelting Furnace Linings

Silicon carbide was fused by heating high purity silicon sand and carbon in electrode furnace above 2500 0C. It is the hardest blasting media available. High-quality silicon carbide media is manufactured to a blocky grain shape that splinters. The resulting silicon carbide abrasives have sharp edges for blasting. Silicon carbide  has a very fast cutting speed and can be recycled and reused many more times than sand. The hardness of silicon carbide allows for much shorter blast times relative to softer blast media.

    Sic 90% Industrial Silicon Carbide Granules for Durable Grinding Applications

    Silicon carbide includes black silicon carbide and green silicon carbide, among which: black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, which are smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp. Green silicon carbide is made from petroleum coke and high-quality silica as the main raw material, adding salt as an additive, and smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum.

    Black Silicon Carbide is brittle and sharp. It has a good electrical and heat conductivity. Its Knoophandness is 3100-3280kg/mm2. 

    Green Silicon Carbide is a synthetic brittle carborundum with high thermal conductivity and high strength which get no decrease in 1000ºC( 7.5 times stronger than Alumina)

    Green silicon carbide is characterized by extreme hardness (Mohs 9.4/2600 Knoop) which only ranks after CBN and B4C.

    The abrasives made of silicon carbide are suitable for working on cast iron,non-ferrous metal,rock, leather,rubber,etc.It is also broadly used as refractory material and metallurgical additive.
