Silicon Metal, an industrial cornerstone, finds its application in a multitude of pivotal sectors, including steel-making, cast iron, and the production of aluminum components for aviation, aircraft, and automobiles. It extends its reach into the silicon optoelectronic device industry, earning the title of the "salt" of modern industries. Crafted from the fusion of quartz and coke within the electric heating furnace, this product boasts a primary silicon content of approximately 98%, with impurities such as iron, aluminum, and calcium composing the remainder.
The creation of Silicon Metal lumps commences in the electric heating furnace, where quartz and coke undergo a redox reaction, transforming into molten silicon liquid. As this liquid cools, it solidifies into substantial primal silicon metal lumps. These large formations are then carefully
segmented into smaller, standardized lumps, typically ranging from 10mm to 100mm. This standard sizing ensures versatility and adaptability for various industrial applications.
Boasting a striking silver or dark gray metallic luster, Silicon Metal is renowned for its high melting point, excellent heat resistance, significant resistivity, and remarkable oxidation resistance, making it an indispensable asset across diverse industries.
1) Silicon Metal is extensively utilized in the refractory material and power metallurgy sectors, where it significantly enhances heat resistance, wear durability, and oxidation resilience, ensuring superior performance and longevity.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as the foundational raw material for the synthesis of high polymers, providing the essential building blocks for innovative polymeric silicon compounds.
3) Industrial silicon powder undergoes sublimation to form monocrystalline silicon, a critical component in the high-tech industry, serving as a pivotal raw material for the creation of integrated circuits and electronic elements, driving forward technological advancements.
4) Within the domains of metallurgy and foundry, industrial silicon powder is esteemed as an additive for iron-based alloys and as a key pharmaceutical ingredient in silicon steel production, thereby enhancing the hardenability and overall performance of steel products.
5) Silicon metal plays a crucial role in the manufacture of high-temperature materials, enabling the production of components that withstand extreme conditions and deliver exceptional durability and reliability.
