Silicon Carbide Green 63C. Grinding Grain F30 Description
Silicon carbide is a ceramic material with outstanding hardness, surpassed only by diamond, cubic boron nitride and boron carbide. The material is highly wear resistant and chemically inert to all alkalis and acids. It also has high temperature resistance. These properties make silicon carbide an excellent abrasive and ceramic material for use in extreme environments.

In silicon carbide production, a mixture of carbon material (usually petroleum coke) and silica or silica sand is chemically reacted at high temperatures in an electrically resistive furnace to form SiC. The resulting crude material is further processed by crushing and grinding to produce SiC grains of the correct shape and size. The grains and powders are either washed with water or chemically treated to achieve higher purity material.
Due to its high refractoriness and thermal conductivity, silicon carbide is widely used in industry in the manufacture of refractory and wear-resistant products. Due to its special properties, silicon carbide refractories are widely used in ferrous and non-ferrous metallurgy, chemical and ceramic industries. High resistance to mechanical effects predetermines their use for lining of the charging zone of blast furnace, glissade guides in the heating furnace. Resistance of the products to non-ferrous metal melts (non-wetting) determined their use in non-ferrous metallurgy for lining the vault, bottom and walls of furnaces. It is expedient to use silicon carbide refractories in muffles, high-temperature recuperators, in the manufacture of capsules and floors for firing ceramic products, covers for thermocouples, sight tubes, etc.
