Overview

Ferroglobe is a representative producer of metallurgical-grade silicon — the bulk commodity silicon that feeds polysilicon purification. (Scaffold stub.)

Position in the chain

• Consumes: high-purity quartz and carbon.
• Supplies: MG-Si to polysilicon makers like Wacker.
• Carbothermic reduction is energy-intensive — see the Energetic Index.
