First, let's discuss the similarities between black and green silicon carbide. Both are produced by smelting quartz sand, petroleum coke, and sawdust at high temperatures in a resistance furnace. However, green silicon carbide requires industrial salt as an additive during smelting. The refined crystals are of high purity, with a hardness between diamond and corundum, and mechanical strength higher than corundum. Black silicon carbide requires no additives, and the smelting time for black silicon carbide is shorter than that for green silicon carbide.
Black silicon carbide is primarily used for processing materials that meet tensile strength requirements, such as glass, ceramics, stone, refractories, cast iron, and non-ferrous metals. Green silicon carbide has excellent self-sharpening properties and is primarily used for machining carbide, titanium alloys, and optical glass. It can also be used for honing cylinder liners and precision grinding high-speed steel tools. Silicon carbide is black, while green silicon carbide is green.
