Silicon Metal is an indispensable cornerstone in modern industrial production, serving vital roles across numerous sectors. This remarkable metal finds extensive use in steel-making, cast iron, aluminum production for aviation, aircraft, and automobile parts, as well as in the innovative field of silicon optoelectronic devices, among others. Often termed the 'salt' of modern industries, Silicon Metal is forged from the fusion of quartz and coke within the intense heat of an electric furnace. The silicon content stands prominently at approximately 98%, with remaining traces of iron, aluminum, and calcium as impurities. This composition underscores its premium quality and utility in high-demand applications.
Silicon Metal lump emerges from a sophisticated process that fuses quartz and coke in an electric heating furnace. Here, the quartz undergoes a transformative redox reaction, transmuting into molten silicon, which subsequently solidifies into large silicon metal lumps upon cooling. These primary formations are initially massive.
Our expert processes craft these large formations into smaller, standardized lumps, aptly named standard size Silicon Metal Lumps, measuring between 10-100mm, tailored to suit various industrial needs.
This exquisite material is characterized by its distinctive silver-gray or dark-gray hue, complete with a metallic luster. It boasts a high melting point, exceptional heat resistance, elevated resistivity, and outstanding oxidation resistance, making it a superior choice for diverse and demanding applications.
1) Silicon Metal is a versatile powerhouse, extensively utilized in the refractory materials and power metallurgy industries. It significantly enhances heat resistance, wear resistance, and oxidation resistance, making it indispensable for high-performance applications.
2) Within the realm of chemical manufacturing, industrial silicon powder serves as the foundational raw material for creating high polymers in organic silicon production.
3) Industrial silicon powder is transformed into monocrystalline silicon, a crucial component in the high-tech sector. It stands as an indispensable raw material in the creation of integrated circuits and electronic elements.
4) In both metallurgy and foundry sectors, industrial silicon powder is highly valued as a critical iron base alloy additive. It plays a pivotal role in the formulation of silicon steel alloys, significantly boosting steel hardenability.
5) Silicon metal is instrumental in the production of materials that withstand extreme temperatures, cementing its status as a vital resource in high-temperature material manufacturing.
