Silicon Metal: The Unsung Hero of Modern Industries! Presenting a vital component in various sectors, Silicon Metal plays a crucial role in steel-making, cast iron, aluminum production for aviation and automobiles, and the creation of silicon optoelectronic devices, among many others. Renowned as the 'salt' of modern industries, this extraordinary material is crafted from quartz and coke in an electric heating furnace. With a prominent silicon content of approximately 98%, the remaining elements include traces of iron, aluminum, and calcium, enhancing its versatile applications.
The production of Silicon Metal lumps involves an intricate process where quartz and coke are transformed in an electric heating furnace. This redox reaction turns quartz into molten silicon, which, upon cooling, solidifies into the large primal silicon metal lumps you see. These are then expertly crafted
into smaller, standard-sized lumps, ranging from 10-100mm. This size customization ensures they meet diverse industrial needs.
With a striking silver-gray or dark gray hue and a metallic sheen, Silicon Metal boasts a high melting point, exceptional heat resistance, significant resistivity, and outstanding oxidation resistance-qualities that make it indispensable in high-performance applications.
1) Silicon Metal is a versatile marvel, finding extensive applications in the refractory material and power metallurgy sectors. It significantly elevates heat resistance, wear resistance, and oxidation resistance, making it indispensable.
2) In the realm of organic silicon chemistry, industrial silicon powder stands as a foundational raw material, vital for the formation of high polymers in organic silicon production.
3) Industrial silicon powder undergoes a transformation into monocrystalline silicon, a critical component in the high-tech industry. It serves as an essential raw material for the fabrication of integrated circuits and electronic components.
4) Within metallurgical and foundry sectors, industrial silicon powder plays the role of an iron-based alloy enhancer and a silicon steel alloy additive, significantly enhancing the hardenability of steel.
5) Silicon metal is a crucial element in the manufacturing of materials capable of withstanding extreme temperatures.
