Silicon Metal is an indispensable industrial powerhouse, pivotal in a myriad of sectors including steel-making, cast iron, and aluminum production for aviation, aircraft, and automotive components. This extraordinary material also plays a crucial role in silicon optoelectronic devices, earning its reputation as the 'salt' of modern industries. Crafted through the sophisticated process of smelting quartz and coke in electric heating furnaces, silicon metal boasts an impressive silicon content of approximately 98%. The remainder comprises trace impurities such as iron, aluminum, and calcium, ensuring its versatility and utility across diverse applications.
Silicon Metal lump production is an art of precision, conducted in electric heating furnaces where quartz undergoes reduction and transforms into molten silicon. Upon cooling, this molten marvel solidifies into its primal form. Initially, these silicon metal lumps are of substantial size.
They are then meticulously refined into smaller, standardized lumps, affectionately known as standard size, with dimensions ranging from 10-100mm, ready for industrial use.
Silver-gray or dark gray in hue, with a metallic sheen, Silicon Metal possesses a formidable high melting point, exceptional heat resistance, and notable high resistivity. Its remarkable oxidation resistance makes it an ideal choice for a wide array of demanding applications.
1) Silicon Metal is extensively utilized in the refractory materials and power metallurgy industries, where it significantly enhances heat resistance, wear resistance, and oxidation resistance, providing unparalleled durability and performance.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as a fundamental raw material for creating high polymers of organic silicon, leading to innovative solutions and advancements in chemical manufacturing.
3) The transformation of industrial silicon powder into monocrystalline silicon plays a crucial role in the high-tech sector, particularly as a vital raw material in the production of integrated circuits and electronic components, driving technological progress and efficiency.
4) Within the metallurgy and foundry sectors, industrial silicon powder is esteemed as an iron base alloy additive and silicon steel alloying agent, thereby enhancing the hardenability and overall quality of steel products.
5) Silicon metal is a key component in the creation of high-temperature materials, offering superior thermal stability and performance in demanding applications.
