The application of black silicon carbide

Because of its stable chemical properties, high thermal conductivity, small thermal expansion coefficient and good wear resistance, black silicon carbide suppliers always sell black silicon carbide, used as abrasives and refractory materials. The following are the application details of black silicon carbide:

1. Abrasive: black silicon carbide due to a certain toughness, mainly used for grinding optical glass, hard alloy, titanium alloy, bearing alloy and bearing steel, as well as high-speed steel tool grinding.

2. Refractory material: black silicon carbide has good thermal shock resistance, so it is a kind of high-quality refractory material. According to the production process of the product, it can be divided into recrystallized black silicon carbide, products, high temperature hot pressing products, with silicon nitride or clay as coupling agent products, etc. The main products and uses are: high temperature furnace components, brackets.

3. Metallurgy industry: new strong compound deoxidizer, replacing the traditional silicon powder and toner deoxidization. In contrast, the physical and chemical properties are more stable, better deoxidation effect, deoxidation time is shortened, slag formation earlier, reduction atmosphere is strong, save energy, improve the efficiency of steelmaking, improve quality, reduce raw and auxiliary material consumption, reduce environmental pollution, improve working conditions, improve the comprehensive benefit of electric furnace.

4. Other fields: electrical industry, black silicon carbide material is also widely used as electric heating elements, high temperature semi-superconductor materials, far infrared plate, lightning arrester valve materials and so on.
