High-purity quartz tube.

High-Purity Quartz Tubes are advanced specialty glass tubes with a silica (SiO₂) purity of ≥99.99%, engineered for extreme industrial environments. Key advantages include:

1、Exceptional High-Temperature Resistance: Softening point up to 1730°C, capable of long-term stability at 1250°C and short-term tolerance up to 1450°C 

2、Superior Corrosion Resistance: Resistant to all acids except hydrofluoric acid, with acid resistance 30× higher than ceramics and 150× higher than stainless steel 

3、Outstanding Thermal Stability: Ultra-low thermal expansion coefficient (5.5×10⁻⁷/°C), withstands rapid temperature changes (e.g., quenching from 1100°C to room temperature without cracking) 

4、Optical & Electrical Performance: UV-to-IR transmittance ≥93%, electrical insulation 10,000× better than standard glass, ideal for fiber optics, lasers, and precision electronics 

5、Customization & Precision: Available in diameters from 1.5mm to 450mm with ±0.1mm geometric accuracy. Dehydroxylation process reduces hydroxyl content to ≤5ppm, preventing crystallization and discoloration
