Product Introduction
Silicon carbide is a non-metallic mineral product produced at high temperatures above 1800 degrees Celsius with quartz sand (SiO2) and petroleum coke (C) as basic raw materials.It has the characteristics of high hardness, small expansion coefficient, brittleness, good thermal conductivity, etc., widely used in abrasive abrasives, electronic products grinding, refractory materials, special ceramics, foam ceramics, coating plastic addition modification, auto parts, military aviation, steel deoxidizer. The company mainly produces various content specifications of black silicon carbide.
Our company supply variety of specifications of silicon carbide, SiC content distribution is: 98%, 95%, 90%, 88%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%. The particle size can be customized according to customer needs, usually 0-1mm, 0-50mm, 1-10mm, 100-400mesh and so on.

（1） Silicon carbide for refractories
In the process of production and processing of black silicon carbide, a large number of silicon carbide content below 90% is formed and produced, commonly known as low silicon.The main uses of low content black silicon carbide for refractory industry, steel industry deoxidizer, clay, castable, iron trench material.
（2） Silicon carbide for deoxidation and casting in steelmaking
Silicon carbide is a compound formed by covalent bond of carbon and silicon, which is a non-oxidizing material.Because of its significant instability in high temperature oxidation atmosphere, especially when the temperature exceeds 1627℃, the oxidation reaction is rapid.The use of this characteristic in the converter and electric furnace smelting general carbon steel and part of the low alloy steel process in order to achieve the purpose of reducing the cost of steelmaking, has achieved good results.Among them, the most commonly used quality is concentrated in 80%-95%, and the particle size is 0-10mm, 0-5mm, 1-3mm, 1-5mm (the most used in casting).
（3）Silicon carbide grit sand
Our company produces silicon carbide particle size sand, the specific product models are: F20, F24, F30, F36, F40, F46, F60, F80, F90, F100, F120, F180, F220, F240, P20, P24, P30, P36, P40, P46, P60, P80, P90, P100, P120, P180, P220, P240.
（4）Silicon Carbide Micro Powder
The application range of silicon carbide powder is more and more wide, and the demand is further increasing.
The silicon carbide powder produced by our company is mainly used in the manufacture of refractory products, foam ceramic industry, solar silicon panel cutting, crystal cutting and grinding, automobile engine parts manufacturing, special coating industry, plastic products modification, desulfurization, power supply, environmental protection industry, etc .
