Comparison of Thermal Properties and Conductivity of Silica Quartz Glass

Chemical properties - acid and alkali resistance

Quartz glass is an acidic material that is inert to any acid except hydrofluoric acid and hot phosphoric acid, making it a good acid resistant material. The corrosion degree of alkali and salt on quartz glass is also small at room temperature, so it is not ruled out to use quartz glass in these reagents.

Regarding the relationship between the thermal properties and electrical conductivity of quartz glass, quartz glass is a high-purity special industrial technical glass containing only silicon dioxide (SiO2) as a single component. Due to its unique properties that cannot be replaced by other materials, such as low thermal conductivity, good thermal shock resistance, high deformation and softening temperatures, low thermal conductivity, low dielectric loss, and optical transmittance over a wide spectral range from ultraviolet to infrared.

Ruisen Optics believes that the price of various types of quartz glass is directly related to the specific material characteristics and processing requirements. Common technical parameters for finished quartz glass:
