Silicon Metal is an indispensable cornerstone of modern industry, celebrated for its versatility and unmatched utility across a multitude of sectors. From the creation of robust steel, precision cast iron, and lightweight aluminum components for aviation, aircraft, and automotive production, to the sophisticated realm of silicon optoelectronic devices, this remarkable material is appropriately deemed the 'salt' of contemporary industries. Crafted through the meticulous smelting of quartz and coke within an electric heating furnace, our silicon metal boasts a silicon content of approximately 98%, with trace impurities including iron, aluminum, and calcium.
The journey of Silicon Metal begins within the confines of an electric heating furnace, where quartz and coke undergo a transformative redox reaction, giving birth to molten silicon. As this molten marvel cools, it solidifies into its primal form-large silicon metal lumps.
These imposing primal lumps undergo careful processing to emerge as standard-sized Silicon Metal Lumps, meticulously crafted to dimensions of 10-100mm.
With a distinctive silver-gray or deep dark-gray hue, Silicon Metal dazzles with its metallic luster. It stands out for its remarkable properties, including a high melting point, exceptional heat resistance, impressive resistivity, and superior oxidation resistance, making it an ideal choice for demanding industrial applications.
1) Silicon Metal is extensively utilized in the refractory materials and power metallurgy sectors. It serves the critical purpose of enhancing heat resistance, wear resistance, and oxidation resistance, proving invaluable in demanding industrial environments.
2) In the realm of organic silicon chemistry, industrial silicon powder stands as the foundational raw material pivotal for the formation of high polymers of organic silicon, driving innovation and excellence in this field.
3) Industrial silicon powder undergoes sublimation into monocrystalline silicon, a fundamental component in the high-tech arena. It is indispensable for crafting integrated circuits and electronic components, propelling advancements in technology.
4) Within the domains of metallurgy and foundry, industrial silicon powder is esteemed as a crucial iron base alloy additive. It plays a vital role as the alloying agent of silicon steel, significantly enhancing the hardenability of steel.
5) The utilization of silicon metal is paramount in the production of high-temperature materials, offering superior performance in extreme conditions.
