Silicon Carbide

What is Silicon Carbide ​

Silicon carbide, an inorganic substance with the chemical formula SiC, is made from quartz sand, petroleum coke (or coal coke), wood chips (salt is added to produce green silicon carbide), and other raw materials smelted at high temperatures in resistance furnaces. Silicon carbide also exists in nature as a rare mineral, moissanite. In C, N, B and other non-oxide high technology refractory raw materials, silicon carbide for the most widely used, the most economical one, can be called gold steel sand or refractory sand. Chinese industrial production of silicon carbide is divided into two kinds of black silicon carbide and green silicon carbide, both hexagonal crystals, specific gravity of 3.20 to 3.25.

Silicon carbide and aluminum oxide are two of the most widely used abrasive materials. Both materials are available in a variety of shapes and sizes, and they can be used for a variety of applications.

Black SiC is suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive.

Green SiC is suitable for processing hard alloy, metallic and non-metallic materials with hard and brittle features such as copper, brass, aluminum, magnesium, jewel, optical glass, ceramics, etc. Super powder of it is also a kind of ceramic material.
