Ferro Silicon Deoxidizer High Quality

Ferrosilicon (FeSi) is an iron-silicon alloy primarily composed of iron (Fe) and silicon (Si), typically containing 15% to 90% silicon by weight. Widely used in steelmaking and foundry industries, it serves as a deoxidizer, alloying agent, and inoculant. Its unique properties enhance the strength, corrosion resistance, and magnetic characteristics of final products. Produced by reducing silica (SiO₂) with carbon in an electric arc furnace, ferrosilicon appears as a metallic gray solid with a crystalline or lumpy structure. Its melting point ranges between 1,200°C and 1,400°C, depending on silicon content.

China, Russia, and Norway dominate global production, accounting for over 70% of output. Quality standards such as ISO 5445 and ASTM A100 ensure consistent chemical composition and particle size distribution. Ferrosilicon is classified as a hazardous material for transport due to potential hydrogen gas emission when wet. With its critical role in metallurgy and growing demand in renewable energy sectors (e.g., silicon solar cells), ferrosilicon remains indispensable for modern industrial processes.
