Silicon Metal stands as a cornerstone in the industrial sector, playing a pivotal role in steel-making, cast iron production, and aluminum manufacturing, essential for aviation, aircraft, and automobile parts. Additionally, it propels the silicon optoelectronic device industry and many others. Renowned as the 'salt' of modern industries, this high-purity silicon is produced from quartz and coke through advanced electric furnace smelting, boasting a silicon content of approximately 98%. The remaining composition includes trace amounts of iron, aluminum, and calcium, ensuring its remarkable versatility and utility.
Produced using state-of-the-art electric furnace technology, Silicon Metal lumps originate from the meticulous reduction of quartz and coke. This process yields molten silicon, which, upon cooling, forms the solid metal lumps we recognize. Initially, these lumps are sizable and subsequently processed
into standard-sized smaller lumps, typically ranging from 10-100mm. This ensures optimal usability and convenience.
Silicon Metal is characterized by its striking silver-gray or dark-gray appearance, enhanced with a metallic luster. It boasts a high melting point, excellent heat resistance, significant resistivity, and superior oxidation resistance, making it invaluable for high-stress industrial applications.
1) Silicon Metal finds extensive application in refractory materials and powder metallurgy, significantly enhancing heat resistance, wear resistance, and oxidation resistance.
2) In the realm of organic silicon chemistry, industrial silicon powder is a fundamental raw material for high polymer organic silicon formation.
3) Sublimated into monocrystalline silicon, industrial silicon powder is indispensable in high-tech fields as a primary raw material for integrated circuits and electronic components.
4) Within metallurgy and foundry industries, industrial silicon powder is a crucial additive to iron-base alloys and silicon steel, enhancing steel hardenability and performance.
5) Silicon Metal also plays a key role in producing high-temperature materials, ensuring exceptional endurance and reliability.
