What are the uses of green silicon carbide? What are the uses of silicon carbide?

1. Abrasives - mainly because silicon carbide has high hardness, chemical stability and certain toughness, so silicon carbide can be used to manufacture consolidated abrasives, coated abrasives and free grinding, so as to process glass, ceramics, stone, cast iron and some non-ferrous metals, cemented carbide, titanium alloy, high-speed steel tools and grinding wheels. 2. Refractory materials and corrosion-resistant materials are mainly --- because silicon carbide has a high melting point (degree of decomposition), chemical inertness and thermal vibration resistance, so silicon carbide can be used in abrasives, ceramic products in the firing furnace of shed plates and sagger, zinc smelting industrial vertical cylinder distillation furnace for silicon carbide bricks, aluminum electrolytic cell linings, crucibles, small furnaces and other silicon carbide ceramic products. 3. Chemical use - because silicon carbide can be decomposed in molten steel and react with ionic oxygen and metal oxides in molten steel to form carbon monoxide and silicon-containing slag.

Therefore, it can be used as a purification agent for smelting steel, that is, as a deoxidizer for steelmaking and a microstructure improver for cast iron. This generally uses low-purity silicon carbide to reduce costs. At the same time, it can also be used as a raw material for the manufacture of silicon tetrachloride.

4. Electrical use - used as heating element, nonlinear resistance element and high semiconductor material. Heating elements such as silicon carbon rods (suitable for all kinds of electric furnaces working in 1100 and 1500), nonlinear resistive elements, and various lightning protection valves. 5.

Silicon carbide has a high hardness, and silicon carbide ceramics made with mature technology have good wear resistance, high temperature resistance and corrosion resistance.

4. Metallurgical raw materials. Currently, an important chemical use of silicon carbide is as a purification agent for steelmaking. Silicon carbide decomposes in molten steel and reacts with free oxygen and metal oxides in molten steel to form carbon monoxide and silica-containing slag.

Silicon carbide is often added to smelting cast iron, so that a small amount of silicon enters the molten iron and promotes the perfection of casting.

According to the use of different purposes:

Silicon carbide is divided into abrasives, refractories, oxygen absorbers, and silicon carbide for electrical applications. The SiC content of silicon carbide for abrasives should be more than 98%. Silicon carbide for refractory materials is further divided into:

2) Secondary refractory black silicon carbide, SiC content greater than 90%;

3) Low-grade refractory black silicon carbide, SiC content greater than 83%. For silicon carbide for oxygen absorber, the SiC content is generally required to be greater than 90%. However, the insulation of the carbon industrial graphitization furnace is guessed that the silicon carbide content is greater than 45%, and it can also be used as a steelmaking deoxidizer after treatment.

There are two types of silicon carbide for oxygen absorber: powder and molded block. Powdered deoxidizer black silicon carbide generally has 4 and two particle sizes.

There are two categories of silicon carbide for electrical applications:
