Description
Additional Information
I. Basic Definition and Material Properties
Quartz columns primarily refer to cylindrical or rod-shaped structures made of high-purity quartz material (SiO? ≥ 99.9%). Their core characteristics include:
- 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.
- Excellent Optical Performance
- Transmittance exceeds 93% from ultraviolet to infrared spectra, making it particularly suitable for laser and optical fiber transmission.
- 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.
