Silicon Metal is an essential powerhouse in the realm of industrial products, serving pivotal roles in an array of industries such as steel-making, cast iron, aluminum production for aviation, aircraft, and automotive parts, as well as in the manufacture of silicon optoelectronic devices. Revered as the 'salt' of modern industries, silicon metal is meticulously crafted from quartz and coke through the art of electric furnace smelting. Its composition boasts approximately 98% pure silicon, with trace impurities of iron, aluminum, and calcium enriching its profile.
The genesis of Silicon Metal lump begins within the electric furnace, where quartz and coke orchestrate a redox reaction, transforming into molten silicon. Upon cooling, this molten marvel solidifies into the primal, large silicon metal lump we observe. This impressive mass undergoes further refinement to reach its next phase.
The substantial primal silicon metal mass is then expertly transformed into smaller, manageable lumps, known as standard size. These Silicon Metal Lumps measure between 10-100mm, perfectly sized for diverse industrial applications.
With a striking silver gray or dark gray appearance, these lumps exude a metallic luster. Notably, Silicon Metal boasts a high melting point, exceptional heat resistance, and remarkable resistivity, coupled with superior oxidation resistance, making it an indispensable element in high-performance environments.
1) Silicon Metal is extensively utilized in the refractory material and power metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as a fundamental raw material pivotal in the formation of high polymers of organic silicon.
3) Industrial silicon powder is transformed into monocrystalline silicon, a critical raw material in high-tech fields, essential for creating integrated circuits and electronic components.
4) Within metallurgy and the foundry sector, industrial silicon powder is prized as an iron base alloy additive and silicon steel alloying agent, significantly enhancing the steel's hardenability.
5) Silicon metal plays a vital role in the production of high-temperature materials.
