Material Properties
Chemical Properties: Quartz glass is an acidic material that is inert to all acids except hydrofluoric acid and hot phosphoric acid. It offers excellent acid resistance with better chemical stability than opaque quartz glass, and is non-hygroscopic and non-weathering.
Electrical Properties: Quartz glass provides high dielectric strength and low conductivity, maintaining excellent dielectric properties even at high temperatures, pressures, and frequencies. With minimal dielectric loss across applied frequency bands, it serves as an outstanding high-temperature dielectric insulation material.
Optical Performance: Quartz glass features unique optical properties, transmitting both far-ultraviolet spectrum (making it ideal for UV-transmitting applications) and visible light with near-infrared spectrum. It offers high temperature resistance, minimal thermal expansion, 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 no cracking allowed after three repetitions.
Mechanical Properties: Quartz glass exhibits superior mechanical properties compared to conventional glass and ceramics, though it maintains some brittleness. While theoretical strength reaches approximately 24*1.3 MPa, actual measured strength is significantly 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 being particularly rapid. This property is especially important for specific user applications.
