Molten quartz high-temperature resistant polished quartz column coatable optical components

 I. Basic Definition and Material Properties

Quartz columns primarily refer to cylindrical or rod-shaped structures made of high-purity quartz material (SiO₂ ≥ 99.9%). Their core characteristics include:

1. Resistance to Extreme Environments
   • High-temperature resistance: Softening point reaches 1730°C, allowing long-term use at 1100°C.
   • Corrosion resistance: Resists most acids and chemical erosion, except hydrofluoric acid and hot phosphoric acid above 300°C.
2. Excellent Optical Performance
   • Transmittance exceeds 93% from ultraviolet to infrared spectra, making it particularly suitable for laser and optical fiber transmission.
3. High Stability
   • Extremely low thermal expansion coefficient with strong thermal shock resistance; electrical insulation performance is 10,000 times that of ordinary glass.

II. Core Application Areas

(1) Semiconductor and Photovoltaic Industries

• Chip Manufacturing: Used as wafer carriers (quartz boats) due to their high-temperature resistance and ability to withstand cosmic rays and nuclear fission byproducts.
• Photovoltaic Equipment: High-purity quartz columns are key consumables in photovoltaic cell production.

(2) Optical and Communication Technologies

• Light-Guiding Components: Cylindrically polished quartz light-guiding columns efficiently direct light into reaction devices for photochemical experiments.
• Laser Focusing: Used as cylindrical lenses and fiber focusing lenses to enhance laser processing precision.
