Silicon Metal is an indispensable powerhouse in the industrial sector, playing a key role across a multitude of fields. It serves as a vital component in steel-making, cast iron, and aluminum production, especially in the aviation, aircraft, and automobile industries. Additionally, it finds applications in silicon optoelectronic devices and numerous other sectors, earning its reputation as the "salt" of modern industries. This exceptional metal is produced through the smelting of quartz and coke in an electric heating furnace, resulting in a product with a predominant silicon content of approximately 98%. The remaining minor impurities include elements such as iron, aluminum, and calcium.
Silicon Metal lump is skillfully crafted in electric heating furnaces using quartz and coke. During the process, quartz undergoes redox transformation, yielding molten silicon liquid. Upon cooling, it solidifies into the substantial silicon metal lump, as we typically recognize it. Initially, the primal silicon metal lumps are remarkably large.
These large primal lumps are expertly reduced into more manageable pieces, referred to as the standard size, typically ranging from 10-100mm. These smaller Silicon Metal Lumps provide versatility in various industrial applications.
Characterized by its silver-gray or dark gray appearance with a striking metallic luster, Silicon Metal boasts remarkable properties. It features a high melting point, exceptional heat resistance, elevated resistivity, and outstanding oxidation resistance, making it a preferred choice for demanding industrial uses.
1) Silicon Metal is extensively utilized across the refractory materials and power metallurgy industries, offering significant enhancements in heat resistance, wear resistance, and oxidation resistance. This versatile metal ensures superior performance and longevity in challenging environments.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as the foundational raw material for the formation of high-polymer organic silicon compounds. Its indispensability in this chemical domain underscores its importance in the production of advanced silicon-based materials.
3) Industrial silicon powder undergoes sublimation to transform into monocrystalline silicon, a critical component in the high-tech industry. As an essential raw material for integrated circuits and electronic elements, it plays a pivotal role in the advancement of technology and electronics.
4) Within the metallurgy and foundry sectors, industrial silicon powder is a key additive to iron-based alloys. It acts as the alloying agent in silicon steel production, thus significantly enhancing the hardenability of steel, resulting in stronger, more durable metal products.
5) Silicon metal is crucial in the manufacture of materials designed to withstand high temperatures, making it an invaluable asset in industries that demand performance at elevated temperatures.
