Product Performance
Metallic silicon powder, also known as industrial silicon powder, is processed from high-purity metallic silicon blocks. The powder appears silver-gray or dark gray with a metallic luster. It features a high melting point, excellent heat resistance, high resistivity, and strong oxidation resistance.
🏆 Often referred to as the "MSG of Industry" — An indispensable fundamental material in many high-tech industries
Applications
1. Refractory & Powder Metallurgy
Widely used in refractory materials and powder metallurgy to improve products' high-temperature resistance, wear resistance, and oxidation resistance. Typical applications include steel-making furnaces, kilns, and kiln furniture.
2. Organosilicon Chemical Industry
Serves as the basic raw material for organosilicon polymer synthesis, used in the production of silicon monomers, silicone oils, silicone rubber, and anti-corrosion agents. Enhances heat resistance, electrical insulation, corrosion resistance, and water repellency.
3. Semiconductor Industry
After being drawn into single-crystal silicon, the processed silicon wafers are widely used in high-tech applications, including integrated circuits and electronic components.
4. Metallurgy & Casting
