Green carborundum 1200#

The particle size of green carborundum 1200# powder is 13-15 microns. It can grind the silicon carbide sealing ring to achieve an ideal finish surface.

Advanced ceramics commonly used in silicon carbide ceramic engineering are applied to mechanical equipment components with high-performance requirements due to their high wear resistance, oxidation resistance, corrosion resistance, high hardness, and good thermal stability. For example, sealing rings, bearings, wear-resistant nozzles, etc. in machinery, metallurgy, equipment manufacturing, shipbuilding, and other industries are made of silicon carbide ceramic materials.

There will be flash edges and burrs of SiC ceramics after getting shapes. It is usually necessary to grind ceramic parts to get a proper fineness. Green silicon carbide is a good grinding medium for this task. Ceramic parts such as silicon carbide sealing rings are usually made from black silicon carbide powder. The SiC purity of green silicon carbide (99%) is higher than that of black silicon carbide (98%). In the meantime, hardness is also higher than that of black silicon carbide. The microhardness of green silicon carbide is 3280-3400kg/mm2 (32-34Gpa). While the microhardness of black silicon carbide is 2840-3320kg/mm2 (28-33gpa). Following the principle of grinding low-hardness materials with high-hardness materials, the grinding effect of green carborundum powder on SiC ceramic parts is obvious. It will get good grinding efficiency.
