Silicon carbide can be used as a new type of composite deoxidizer in the steelmaking process. Compared with traditional silicon powder and carbon powder for deoxidation, silicon carbide alloy has more stable physical and chemical properties, faster deoxidation speed, and shorter deoxidation time. It can save energy, improve steelmaking efficiency, improve steel quality, and reduce raw and auxiliary materials. consumption, reduce environmental pollution, and improve the comprehensive economic benefits of electric furnaces.

Green Silicon Carbide (GSC) is a special type of silicon carbide material, the main components of which are silicon (Si) and carbon (C), and usually contain small amounts of impurity elements such as nitrogen (N) and iron (Fe). It has unique physical and chemical properties and is suitable for a variety of advanced applications.

Physical properties

1. Color and appearance:

The name of green silicon comes from its color, which usually presents a green or light green appearance. This color is formed due to the special treatment method during its production process.

2. Structure:

Green silicon has a crystal structure similar to black silicon carbide, usually 4H-SiC or 6H-SiC structure. This structure gives it high hardness and excellent wear resistance.

3. Hardness:

The hardness of green silicon is very high, close to that of natural diamonds, making it suitable for the processing and application of high hardness materials.

Main uses

1. Abrasive:

Green silicon carbide is widely used as a high-performance abrasive, especially for processing and polishing materials with high hardness, such as metals, ceramics, glass, etc. Its high hardness and wear resistance enable it to provide effective grinding and polishing effects.

2. Ceramic industry:

In the ceramic industry, green silicon carbide is often used to manufacture high-performance wear-resistant ceramic materials and high-temperature resistant ceramic components, such as cutting tools, bearings, seals, etc.

3. Electronics industry:

Due to its excellent electronic properties and high thermal conductivity, green silicon carbide is also used to manufacture high-power electronic devices, optoelectronic devices and semiconductor materials, such as power modules, radio frequency devices, etc.

4. Other applications:

In addition, green silicon is also used in the manufacture of photovoltaic materials, chemical reaction catalysts and high-temperature wear-resistant coatings, providing excellent performance and reliability.
