  Detailed Description: Silicon carbide is mainly classified into black silicon carbide and green silicon carbide. Silicon carbide, also known as carborundum, is the most widely used and most economical non-oxide hi-tech refractory materials among current C, N and B nonoxide refractory materials. It is also known as fire sand.
Green silicon carbide is smelted mainly with petroleum coke and high-quality silica as raw materials in resistance furnace, with edible salt added as the additive; it is green, with high hardness, good cutting capacity, stable chemical properties and good heat conductivity. It is of high purity and fragile, with the micro hardness of 3280--3400 kg/mm2.
The abrasive tools made from green silicon carbide are applicable to processing materials with great hardness and high fragility. Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum. Green silicon carbide is mainly used in grinding hard metal-bearing tools.
Green silicon carbide contains over 99% SiC, with good self-sharpening ability; is mostly used in processing hard alloys, titanium alloy and optical glass; it is also used to grind cylinder sleeve and precisely grinding of high-speed steel knives.
