Black silicon carbide (Black carborundum) is an artificial abrasive media. The SiC content of A-grade black silicon carbide is up to 98%.  After chemically treated, black silicon carbide purity can reach 99%. Although the hardness is not as high as that of green silicon carbide, black silicon carbide is excellent for grinding such as ceramics, stone, and wear-resistant coatings.

Green silicon carbide has excellent thermal properties such as good high-temperature resistance. And it’s wear-resistant and anti-corrosion. Green silicon carbide powder for ceramic foam insulation products is well used in the construction field.

In March 2022, the editor once published industry trends, when the price increase trend of green silicon carbide abrasives had already begun to emerge. 3 months have passed, what is the current price of green silicon carbide? When will the price increase of green silicon carbide abrasive material stop?

Generally, Carborundum refers to silicon carbide whose crystal phase is α phase. Carborundum includes green silicon carbide and black silicon carbide according to the purity of SiC. The purity of green silicon carbide is slightly higher than that of black silicon carbide.
