Silicon Metal 97 10-100mm is a premium industrial silicon product with a silicon content of ≥97% (grade-specific up to 99%), featuring an optimized lump size range of 10~100mm. Smelted in electric furnaces using high-purity silica and carbonaceous reducing agents (lignite, coke), this alloy undergoes strict quality control to minimize impurities (Fe ≤0.5%, Al ≤0.5%, Ca ≤0.3%) and ensure uniform particle distribution. As a cost-effective alternative to high-purity silicon metal, it excels as a deoxidizer, alloying agent, and raw material-delivering reliable performance in metallurgy, chemical synthesis, electronics, and more, while optimizing production efficiency and reducing operational costs.
