Silicon Briquette 70
Silicon Briquette 70 (SiBriq70)
The Gold Standard for Advanced Steel & Titanium Applications
Precision-Crafted for Critical Applications!
Silicon Briquette 70(SiBriq 70) is a high-purity silicon briquette containing ≥70% silicon, designed for industries requiring exceptional metallurgical control. With ultra-low impurities (Al ≤0.8%, S ≤0.01%), it is ideal for solar silicon purification, aerospace alloys, and advanced electronics manufacturing.

Why Silicon Briquette 70 Stands Out?
Elite Purity for High-Tech Innovation!
✅ Rapid Deoxidation: Silicon content ≥70% ensures 30% faster reaction kinetics in EAF/BOF furnaces.
✅ Ultra-Low Impurities: ≤0.01% sulfur/phosphorus prevents hot shortness and embrittlement in aerospace alloys.
✅ Cost-Efficient Scalability: Balances premium purity with 20% lower cost vs. SiBriq 75 for industrial-scale operations.
✅ Eco-Friendly Manufacturing: Produced using 100% renewable energy at Fengyang's zero-emission facility.
✅ Longer Tool Life: Reduced slag formation by 25% extends furnace lining lifespan.
✅Ultra-Low Contaminants: ≤0.8% Al and ≤0.01% S ensure minimal inclusion formation.
✅Rapid Melting: 45% faster dissolution than standard briquettes, reducing energy costs.
✅Gas-Free Structure: Electron-beam refined to <0.05% gas porosity for flawless performance.
✅Certified Quality: ISO 17025 lab reports with traceable batch certification.
