Silicon Metal is an indispensable powerhouse in the realm of modern industry, celebrated for its versatility and critical applications. Whether it's enhancing steel-making processes, fortifying cast iron, or taking flight in aluminum parts for aviation and automobiles, this extraordinary product is integral to the creation of silicon optoelectronic devices and a myriad of other industries. Often hailed as the "salt" of contemporary manufacturing, this remarkable metal is crafted through the sophisticated smelting of quartz and coke in an electric heating furnace. With a primary silicon content of approximately 98%, it is a pure marvel of industrial engineering, with impurities such as iron, aluminum, and calcium being minimal.
Silicon Metal lumps are born from a meticulous process in an electric heating furnace where quartz and coke undergo a transformative redox reaction, resulting in molten silicon liquid. This molten marvel cools to form the solid silicon metal lumps we admire. Initially cast in large, impressive forms, these lumps undergo further refinement.
to become the versatile standard-sized lumps, expertly reduced to a manageable size range of 10-100mm. These silicon metal lumps are engineered for convenient handling and diverse industrial applications.
With a striking silver-gray or dark gray hue and a captivating metallic luster, Silicon Metal boasts a high melting point and exceptional heat resistance. Its high resistivity and superior oxidation resistance make it a formidable material in various demanding environments and advanced applications.
1) Silicon Metal is celebrated for its versatile applications in the refractory material and power metallurgy industries, where it stands out for its remarkable ability to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as the foundational raw material in the synthesis of high-performance organic silicon polymers.
3) Industrial silicon powder is transformed into monocrystalline silicon, a vital component within the cutting-edge technology sector, playing a critical role as a fundamental material for integrated circuits and electronic elements.
