Quartz

For manufacturers of Ferrosilicon (FeSi) and Silicon Metal, the quality of quartz is the single most critical factor in determining furnace efficiency, energy consumption, and final product purity.  We supply quality quartz which are carefully graded for our customers.

High-Purity Quartz for Electrometallurgy

Our quartz is specifically sourced and processed to meet the rigorous demands of submerged arc furnace (SAF) operations. 

Core Product Applications

  • Ferrosilicon Production: High-purity silica serves as the primary silicon source. Our quartz ensures optimal Si recovery while minimizing slag formation.
  • Silicon Metal (Metallurgical Grade): For high-purity applications, we provide quartz with extremely low metallic impurities (Al, Ca, Ti), essential for high-grade silicon used in aluminum alloying and chemical industries.
  • Specialty Alloys: Consistent lump sizing and high thermal stability make our quartz ideal for producing specialized ferroalloys for the solar and semiconductor precursor markets. 

Key Performance Indicators

  • Thermal Stability & Burst Resistance: Our quartz is tested for high “furnaceability,” meaning it maintains its structural integrity as it descends into the furnace, preventing fines that clog gas permeability.
  • High Reactivity: Optimized for the carbothermic reduction process (SiO2 + 2C – Si + 2CO), ensuring rapid conversion with minimal energy waste.
  • Minimal Slag Generation: Low levels of Al2O3 and CaO prevent the formation of high-viscosity slag, which can damage furnace linings and increase power costs.
