Silicon Metal is an indispensable industrial commodity with extensive applications in steel-making, cast iron, aluminum production (including aviation, aircraft, and automobile parts), silicon optoelectronic devices, and various other industries. Revered as the 'salt' of modern industries, metal silicon is derived from quartz and coke through an electric heating furnace smelting process. The primary component, silicon, comprises approximately 98% of the content, with the remainder consisting of trace impurities such as iron, aluminum, and calcium.
Silicon Metal lump is produced by smelting quartz and coke in an electric heating furnace. This process results in the reduction of quartz to molten silicon, which solidifies upon cooling to form large silicon metal lumps.
These large lumps are then processed into smaller, standard-sized lumps ranging from 10-100mm, known as Silicon Metal Lumps.
Silicon Metal Lumps exhibit a silver-gray or dark gray hue with a metallic luster. They are characterized by a high melting point, excellent heat resistance, high resistivity, and superior oxidation resistance.
1) Silicon Metal is extensively used in refractory materials and the power metallurgy industry to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the chemical industry, industrial silicon powder serves as a fundamental raw material for the synthesis of high polymers in organic silicon.
3) Industrial silicon powder is converted into monocrystalline silicon, a crucial material in the high-tech sector for producing integrated circuits and electronic components.
4) Within metallurgy and foundry sectors, industrial silicon powder is utilized as an iron base alloy additive and a pharmaceutical agent for silicon steel, thereby enhancing the hardenability of steel.
5) Silicon metal plays a vital role in manufacturing high-temperature-resistant materials.
