Technical Properties
Chemical Properties
Quartz glass is an acidic material that is inert to all acids except hydrofluoric acid and hot phosphoric acid. It serves as an excellent acid-resistant material with better chemical stability than opaque quartz glass, and is non-hygroscopic and non-weathering.
Electrical Properties
Quartz glass exhibits high dielectric strength and low conductivity, maintaining these properties even at high temperatures, pressures, and frequencies. With minimal dielectric loss across applied frequency bands, it serves as an excellent high-temperature dielectric insulation material.
Optical Performance
Quartz glass possesses unique optical properties, transmitting both far-ultraviolet spectrum (making it ideal for UV-transmitting applications) as well as visible light and near-infrared spectrum. It features high temperature resistance, minimal thermal expansion coefficient, excellent chemical thermal stability, and optical quality comparable to general optical glass.
Thermal Properties
The thermal expansion coefficient of quartz glass is exceptionally small—only 1/12 to 1/20 that of ordinary glass. Standard testing involves heating specimens to 1200°C and then rapidly quenching in cold water, with the material required to withstand this process more than three times without cracking.
Mechanical Properties
Quartz glass demonstrates superior mechanical properties compared to conventional glass and ceramics, though it exhibits some brittleness. While theoretical calculated strength reaches approximately 24*1.3 MPa, actual measured strength values are typically several tens of times lower.
Airtight Performance
The relaxed structure of quartz glass allows certain gas ions to diffuse through the network even at high temperatures, with sodium ion diffusion occurring relatively quickly. This property is particularly important for specific industrial applications.
