Silicon carbide (SiC) 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. SiC 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. Huamao (Gansu) New Material Technology Co., Ltd. mainly produces black silicon carbide and green silicon carbide in various content specifications.
| Silicon Carbide Type Name | Characteristics | Chemical composition | |
| SIC granularity | Particle size | ||
| Silicon carbide refractory | sand black coarse crystal | 90%-98% | 0-10mm, 1-5mm, 0-1mm |
| Ordinary silicon carbide refractory | sand black coarse crystal | 80%-90% | 0-10mm, 1-5mm, 0-1mm |
| Economical silicon carbide refractory | sand black coarse crystal | 30%-70% | 0-10mm, 1-5mm, 0-1mm |
| Application Direction | Silicon Carbide | Description |
| Sandblasting and engraving | black | generally purchase F36, F46, and the content requirement is about 97.5-98%; for export orders, the content requirement is between 98-98.5%. Such materials have hardness and cleanliness requirements. |
| Grinding wheel and sandpaper | black | generally 46#-90#, the grinding wheel uses F standard; the sandpaper uses P standard. |
| Brake pads | black | generally use CF500# and CF600# materials. |
| Furnace wall coating | black | generally uses 97% 325mesh. |
| Abrasives | Black | Customers purchase products concentrated in coarser grades than F220, with F46, F60, and F80 performing better. |
(1) Silicon carbide SIC for refractory materials: Our company offers silicon carbide with various specifications ranging from 98% to 40% content distribution. This product is commonly used in the refractory and steelmaking industries for applications such as deoxidizers, gun mud, castables, and trench materials. Customizable particle sizes include 0-1mm, 0-50mm, 1-10mm, and 100-400mesh.
(2) Silicon carbide for steelmaking deoxidation and casting: Silicon carbide, with a quality concentration of 80%-95%, is an ideal replacement for ferrosilicon and carburizing agents in the steelmaking process. It helps deoxidize, heat, and increase silicon and carbon in molten steel, reducing steelmaking costs effectively. Commonly used particle sizes are 0-10mm, 0-5mm, 1-3mm, and 1-5mm, especially suitable for casting applications.
