company news about green silicon carbide and black silicon carbide difference

Green silicon carbide and black silicon carbide are basically the same, but the raw materials and smelting process are different. Green silicon carbide is green and has higher hardness and purity than black silicon carbide.Black silicon carbide contains about 98.5% SiC and its toughness is higher than that of green silicon carbide. It is mainly used for processing low tensile strength materials such as glass, ceramics, stone, refractory, cast iron and non-ferrous metals.

Green silicon carbide contains more than 99% SiC and has good self-grinding performance. In addition, there is cubic silicon carbide, which is a yellow-green crystal obtained by a special process. Grinding tools used to manufacture bearings are suitable for super finishing of bearings.
Green silicon carbide chemical coefficient: due to its stable chemical properties, high thermal conductivity, small thermal shrinkage coefficient, good wear resistance, in addition to abrasive, there are many other uses; Small size, light weight, high strength, good energy saving effect.
Green silicon carbide is suitable for grinding copper, brass, aluminum, precious stones, optical glass, ceramics and other hard alloys, metals and hard brittle non-metallic materials. Its powder can also be used as a ceramic material. Because of its high purity, black silicon carbide is also commonly used in the manufacture of refractories and various grinding tools.

Black silicon carbide from quartz sand, petroleum coke and high quality silicon dioxide as the main raw materials, in resistance furnace high temperature melting. Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum, and it is brittle and sharp.
