🌟 FG Quartz High-Purity Quartz Glass Products for Semiconductor & Solar Applications

🔬 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 (≥99.99% SiO₂), 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 (~0.5×10⁻⁶/K): Minimizes stress during thermal cycling.
  • High Softening Point (~1700°C): Ideal for processes exceeding 1100°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.

⚙️ FG Quartz Glass Manufacturing Process

We employ advanced melting, shaping, machining, and finishing techniques to ensure our quartz products meet precise specifications:

  1. Material Selection & Melting:
    • Ultra-pure SiO₂ is melted in arc or induction furnaces.
  2. Forming Methods:
    • Drawing: For quartz tubes and rods
    • Blowing: For complex cavities
    • Casting: For plates, blocks, and large parts
  3. Precision Machining:
    • Cutting, drilling, CNC turning, and milling
  4. Annealing:
    • Removes internal stress for enhanced thermal and mechanical performance
  5. Surface Finishing:
    • Polishing: Mirror-like surfaces reduce contamination risk
    • Flame Polishing: Smooths edges to prevent cracking
  6. Quality Assurance:
    • Includes purity analysis, thermal and optical tests, and dimensional inspections
