How much does silicon carbide cost?

The price of silicon carbide is about one to two thousand yuan per ton, ranging from a few hundred yuan to a few thousand yuan. Different types of silicon carbide have different prices.

In terms of category, silicon carbide has two commonly used basic varieties: black silicon carbide and green silicon carbide, both of which belong to α-SiC.

① Black silicon carbide contains about 95% SiC, and its toughness is higher than green silicon carbide. It is mostly used to process materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.

② Green silicon carbide contains more than 97% SiC and has good self-sharpening properties. It is mostly used for processing cemented carbide, titanium alloy and optical glass. It is also used for honing cylinder liners and fine grinding of high-speed steel cutting tools.

In addition, there is cubic silicon carbide, which is a yellow-green crystal produced by a special process. The abrasive tools used to make it are suitable for ultra-finishing of bearings, and can make the surface roughness from Ra32 ~ 0.16 microns to Ra0.04 ~ 0.02 micron.
