Black silicon carbide is smelted in a high-temperature resistance furnace using quartz sand and petroleum coke as the main raw materials. The crystal is black and has a microhardness of 2800-3300Kg/mm². It is used to make abrasive tools, suitable for processing metals and non-metallic materials with low tensile strength, such as gray cast iron, brass, aluminum, stone, leather, and hard rubber. wait. In addition, it can also be used in refractory materials, electronic industry, etc.
High-purity silicon carbide is not always black or green. Pure silicon carbide is actually colorless. Its color actually changes with the processing of industrial silicon carbide, and the color changes with the content and shape of inclusions. The carbon melted in the crystal causes the crystal to appear dark blue or black. Crystals without carbon elements doped into it appear green. The green color mentioned here also varies from light green to light yellow to brown depending on the amount of the element. The crystal shape of silicon carbide is generally cubic, rhombohedral or hexagonal. When there is an excess of carbon in the crystal, radial needles form. The specific gravity of silicon carbide is -3.39, and its hardness is between corundum and boron carbide, which is 9.2. The volume specific gravity of silicon carbide particles varies from particle to particle. Particles with diameters in the range of 0.125-0.150 mm have larger volume specific gravity values; particles with diameters of 1.7-2.0 mm and 0.028-0.042 mm have smaller volume specific gravity values. In most cases, silicon carbide can be used as a deoxidizer and a carburizing inoculant, playing an important role in the process of casting steel and iron.
