Silicon Metal is an indispensable industrial material with applications spanning steel-making, cast iron, aluminum manufacturing (including aviation, aircraft, and automobile parts), and the silicon optoelectronic device sector, among others. This material, often referred to as the 'salt' of modern industries, is produced from the smelting of quartz and coke in electric heating furnaces. It boasts a silicon content of approximately 98%, with the remaining impurities comprising iron, aluminum, and calcium.
The creation of Silicon Metal lumps involves the use of electric heating furnaces where quartz undergoes redox reactions to become molten silicon. Once cooled, it solidifies into the large primal silicon metal lumps.
These lumps are then broken down into smaller, standard-sized pieces, typically measuring between 10-100mm.
With a striking silver-gray or dark gray hue and a metallic luster, Silicon Metal is celebrated for its high melting point, exceptional heat resistance, high resistivity, and superior oxidation resistance.
1) Widely utilized in the refractory material and power metallurgy industries, Silicon Metal enhances heat resistance, wear resistance, and oxidation resistance.
2) In the chemical sector, industrial silicon powder serves as the foundational raw material for the synthesis of high polymers in organic silicon production.
3) As a crucial material in high-tech fields, industrial silicon powder is sublimated to produce monocrystalline silicon, essential for integrated circuits and electronic components.
4) Within the metallurgy and foundry sectors, industrial silicon powder acts as an additive to iron base alloys and as a pharmaceutical component in silicon steel, thus improving the hardenability of steel.
5) Silicon Metal is also integral to the production of high-temperature materials.
