Quartz for silicon metal & ferroalloys

Quartz pebbles for silicon metal

Silicon metal production requires quartz with very high silica content, low impurity levels and stable behaviour under extreme furnace conditions. Imerys supplies quartz pebbles for silicon metal production from its quarries in southwest France, known for their high silica content and consistent quality. These materials are designed for use in electric arc furnaces and support stable and efficient reduction processes.

Key characteristics:

• Very high silica content (up to 99.8% SiO₂)
• Low iron and titanium levels
• Controlled pebble size distribution
• High thermal stability
• Chemically inert behaviour during reduction

These properties contribute to stable furnace operations, efficient silicon yield and consistent silicon metal quality.

High-purity quartz pebbles for the ferro-silicon industry

Ferro-silicon alloy production demands high-quality quartz combining controlled chemistry and good physical integrity to ensure stable performance in submerged arc furnaces. 
Imerys offers high-purity quartz pebbles that meet stringent chemical purity requirements, where impurities directly affect alloy performance.

Key features
    •    High SiO₂ content
    •    Low impurities level
    •    Good mechanical strength
    •    High thermal stability
    •    Consistent behaviour supporting furnace permeability and process stability
