Why is silicon carbide green and black?
Black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, and is smelted by resistance furnace at high temperature.
The raw materials used in the manufacture of green silicon carbide, such as black silicon carbide, are roughly the same, and industrial salt is used as a reactant and accelerator to react in a resistance furnace.
In terms of its color, it is green, so it is named green silicon carbide. In addition to the difference in color, in general, green silicon has good sharpness and black silicon has good toughness. Different from where they are used. The texture of green silicon carbide is purer than that of black silicon carbide, and its hardness is higher than that of black silicon carbide. Its grinding purpose is the same as that of black silicon carbide, and it is more suitable for fine grinding of materials such as thread grinding and measuring tools. Grinding materials are more widely used for workpieces of cemented carbide and diamond products.

In terms of its color, it is green, so it is named green silicon carbide. What about black and green? In addition to the difference in color, in general, black silicon has good toughness.
