Silicon nitride bonded silicon carbide takes quartz, petroleum coke as raw materials, gouache, salt as auxiliary material, which are put into resistance furnace for temperature smelting.
Silicon nitride bonded silicon carbide can be black and green: Black silicon nitride bonded silicon carbide black or blue-black, green silicon nitride bonded silicon carbide green or blue-green. In the manufacturing process, the production of green silicon nitride bonded silicon carbide is characterized by the use of purer raw materials, charge added salt, it can promote the product green. Green silicon nitride bonded silicon carbide purity than black silicon nitride bonded silicon carbide. Silicon nitride bonded silicon carbide does not react with any acid, alkali oxides melt but can promote the decomposition of silicon nitride bonded silicon carbide.

Black silicon nitride bonded silicon carbide and synthetic corundum abrasives compared with high hardness, brittleness, suitable for processing low tensile strength of the metal and non-metallic materials, such as gray cast iron, brass, non-ferrous metals such as lead, and ceramics, glass and other hard materials brittle material. Green silicon nitride bonded silicon carbide and silicon nitride bonded silicon carbide black compared to its purity, hardness, slightly brittle material suitable for processing hard and brittle, such as cemented carbide, glass, agate, also widely used measuring tools, cutting tools, molds grinding and aircraft, automobiles, shipbuilding and other engine cylinder honing.
