Black silicon carbide is quartz sand, petroleum coke and quality silica as the main raw material in electric arc furnace smelting. Its hardness between corundum and diamond, the mechanical strength is higher than corundum, brittle and sharp. Black silicon carbide SiC containing approximately 98.5% higher than its toughness green silicon carbide, mostly for processing low tensile strength of the material, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.

Silicon carbide purpose
Black silicon carbide semiconductor can handle "extreme environment", it is alleged that silicon carbide wafer can withstand even Venus or near the sun's heat. Previous studies show that even at a temperature of 560 degrees Celsius, silicon carbide wafer in the absence of cooling device is still functioning normally. calcium siliconwafer has wide applied prospects in the field of communication, can let the high-definition TV transmitters provide a clearer signal and image; Also can be used in jet and automobile engine, monitoring the motor running. At the same time, it also can be used in the field of space exploration, help nuclear-powered spacecraft perform more complex tasks. French physicist predicted that in the field of chip manufacturing silicon carbide replace silicon has been far too.
