π FG Quartz High-Purity Quartz Glass Products for Semiconductor & Solar Applications
π¬ Quartz Glass: Core Properties & Importance in Modern Manufacturing
Quartz glass for semiconductor and solar energy applications is essential due to its unmatched purity, thermal resistance, and chemical stability. FG Quartz offers ultra-high purity quartz glass (β₯99.99% SiOβ), engineered to meet the rigorous demands of semiconductor fabrication and photovoltaic cell production.
Key Physical Characteristics:
- Extreme Purity: Prevents contamination and improves device yield.
- Low Thermal Expansion (~0.5Γ10β»βΆ/K): Minimizes stress during thermal cycling.
- High Softening Point (~1700Β°C): Ideal for processes exceeding 1200Β°C.
- Excellent Thermal Shock Resistance: Resists cracking during rapid temperature changes.
- Superior Chemical Inertness: Stable against acids (excluding HF), perfect for wet etching and cleaning.
- Exceptional Optical Transparency: High transmission from UV to IR range.
