Silicon Metal is a pivotal industrial cornerstone, renowned for its versatile applications across a spectrum of industries including steel-making, cast iron, and the production of aluminum components for aviation, aircraft, and automobiles. Furthermore, it plays a crucial role in silicon optoelectronic devices and numerous other sectors, earning it the moniker of the "salt" of modern industries. This remarkable metal is synthesized from quartz and coke through smelting in an electric heating furnace, boasting a silicon content of approximately 98%. The remaining composition includes impurities such as iron, aluminum, and calcium.
Silicon Metal lumps are crafted through an intricate process in an electric heating furnace, utilizing quartz and coke. Here, the quartz undergoes reduction and transforms into molten silicon liquid. Upon cooling, this liquid solidifies into the substantial silicon metal lumps we recognize.
These original silicon metal lumps are sizable and are subsequently processed into smaller, standardized lumps, known as Silicon Metal Lumps, measuring anywhere from 10 to 100mm in size.
Characterized by its striking silver-gray or dark gray appearance, Silicon Metal exudes a metallic luster. It is celebrated for its high melting point, exceptional heat resistance, elevated resistivity, and outstanding oxidation resistance.
1) Silicon Metal is an indispensable element in the realm of refractory materials and power metallurgy industries. It significantly enhances heat resistance, wear resistance, and oxidation resistance, making it an ideal choice for robust metallurgical processes.
2) In the world of organic silicon chemistry, industrial silicon powder serves as a fundamental raw material for the formation of high-performing organic silicon polymers, driving innovation and efficiency in chemical applications.
3) Industrial silicon powder is sublimated to create monocrystalline silicon, a critical component in the high-tech industry. It is essential for the fabrication of integrated circuits and electronic elements, propelling advancements in technology.
4) Within the metallurgy and foundry sectors, industrial silicon powder acts as a vital additive to iron-based alloys and a pharmaceutical agent in silicon steel. This significantly enhances the hardenability of steel, contributing to stronger and more durable metal products.
5) Silicon metal plays a pivotal role in the production of high-temperature materials, offering unmatched stability and performance in demanding thermal environments.
