Silicon carbide is a non-metallic mineral product produced from quartz sand (SiO2) and anthracite or petroleum coke (C) as basic raw materials at high temperatures above 1800 degrees Celsius. It has high hardness, small expansion coefficient, brittleness and good thermal conductivity. With its characteristics, it is widely used in abrasive grinding tools, electronic product grinding, refractory materials, special ceramics, foam ceramics, additive modification of coating plastics, auto parts, military aviation, deoxidizers for steelmaking, etc. The company mainly produces black silicon carbide and green silicon carbide in various content specifications.
Product performance
1. High chemical stability, low thermal expansion coefficient, high thermal conductivity, and resistance temperature characteristics are opposite to those of metals;
2. High hardness, with Mohs hardness reaching 9.5, it is the first wear-resistant additive for materials;
3. Wear-resistant, high temperature resistant, corrosion resistant, acid and alkali solvent resistant, widely used in coatings and paints to increase wear resistance;
4. It has good toughness, excellent grinding performance, and excellent electrical dissipation and thermal conductivity.
