Quartz Glass Properties and Applications in Optics and Space
Quartz Glass Properties:
-
Excellent Spectral Transmittance and Optical Uniformity: Quartz glass properties make it widely used in the optical field, especially in semiconductor lithography and precision optical devices. Its excellent spectral transmittance and optical uniformity make quartz glass the material of choice in these applications.
-
Good Radiation Resistance: Another key quartz glass property is its good radiation resistance, allowing it to be used in crucial components of spacecraft and space laboratories. For example, it is used as window materials for the “Shenzhou” series of spacecraft and the “Tiangong” series of space experiments.
-
High Purity and Performance: Quartz glass, along with borosilicate glass, represents high-purity, high-performance special glasses. The unique quartz glass properties differ significantly from ordinary glass in terms of composition, manufacturing process, and applications.
-
Transparency: Quartz glass exhibits good transparency in the ultraviolet range, whereas borosilicate glass primarily offers transparency in the visible range.
-
Corrosion Resistance: The corrosion resistance of quartz glass is another important property, making it suitable for specific application scenarios.
-
Anti-fading and Anti-aging: Quartz glass has a strong ability to resist fading, ensuring that its color remains stable over time.
-
Composition and Temperature Resistance: The main component of quartz glass is silica, with a purity of up to 99.99%. In contrast, high borosilicate glass contains sodium oxide, boron oxide, and silica, resulting in different temperature resistance properties.
-
Less Dense: Quartz glass is less dense than other types of glass, making it advantageous for applications requiring lightweight materials.
In summary, the unique advantages of quartz glass properties—such as excellent spectral transmittance, good radiation resistance, high purity, and corrosion resistance—make it widely used in optical devices, spacecraft, space laboratories, and other fields.
