The differences between Black silicon carbide and green silicon carbide
Both black silicon carbide and green silicon carbide are smelted from quartz sand, petroleum coke and wood chips through a resistance furnace at high temperature, but green silicon carbide is smelted with industrial salt as an additive. Here is how to distinguish between black silicon carbide and green silicon carbide:
Black silicon carbide does not require additives, and the smelting time of black silicon carbide is lower than that of green silicon carbide. Then black silicon carbide is mainly used to process materials that resist tensile strength, such as glass, ceramics, stone, refractory materials, cast iron, non-ferrous metals, etc.;
Green silicon carbide has good self-sharpening, and is mainly used for processing hard alloys, titanium alloys and optical glass. It is also used for honing cylinder liners and accurately grinding high-speed steel stealing tools and so on.
The production cost of green silicon carbide is higher than that of black silicon carbide. If the ratio of raw materials is different, there are auxiliary materials of salt, and the difference in power consumption and processing process. Therefore, the price of green silicon carbide is higher than that of black silicon carbide. Silicon carbide is higher. Therefore, the selection of green silicon carbide is compared with black silicon carbide. In terms of non-metallic and non-ferrous metal materials, green silicon carbide is generally not used, and green silicon carbide is mainly used for the grinding of cemented carbide and accurate grinding. Even fewer choose green silicon carbide as the grinding material on abrasive belts and other coated abrasive tools. In terms of color, black silicon carbide is black, and green silicon carbide is green.
