Silicon metal 553 is an industrial-grade silicon-based material, which is smelted by high temperature in an electric furnace with quartz sand and carbonaceous reducing agent. The silicon content is ≥98.5%, and the impurity contents of iron, aluminum and calcium are controlled within 0.5%, 0.5% and 0.3% respectively. It is an ideal raw material in the fields of metallurgy, chemical industry and new energy. The product is silver-gray block or customized particles, with hard texture, high surface gloss, excellent high temperature resistance, conductivity and chemical stability. Silicon metal 553 has semiconductor properties, and its conductivity increases significantly with increasing temperature. Its production process is mature. It is cost-effective, with moderate impurity content, meets industrial-grade needs, and the cost is lower than that of high-purity silicon metal. Silicon metal 553 particles are uniform and easy to break, suitable for rapid dissolution in aluminum melt or refractory formulations.
Silicon metal 553 is widely used in aluminum alloy manufacturing, casting, refractory materials and silicone industries, and is an indispensable basic raw material in the industrial field. Metal silicon 553 strictly complies with international standards (such as GB/T 2881-2014), has passed ISO quality system certification, and has both high cost performance and environmental protection attributes. It is a reliable choice for industrial upgrading and green manufacturing.
