Comparison of the relationship between thermal properties and electrical conductivity of transparent quartz glass

        The conductivity of transparent quartz glass is 10-17-10-16 West/m, and the conductivity of opaque quartz glass is 10-14-3.2×10-13 West/m, and its value is related to the purity of quartz glass. The dielectric constant of Xiamen Yiweit quartz glass is at room temperature and 0-106 Hz frequency, the dielectric constant of transparent quartz glass is 3.70; opaque quartz glass is 3.50, the temperature increases, the dielectric constant increases slightly, after 450oC , the dielectric constant increases significantly.

        Dielectric loss

        The relationship between the dielectric loss of quartz glass and the temperature is that with the increase of temperature, the dielectric loss increases. Above 350oC, the dielectric loss increases more significantly with the increase of temperature.

        Chemical Properties - Acid and Alkali Resistance Quartz glass is an acid material. Except for hydrofluoric acid and hot phosphoric acid, it is inert to any other acid and is the best acid-resistant material. The degree of corrosion of quartz glass by alkalis and salts at room temperature is also extremely small, so the use of quartz glass in these reagents is not excluded.

        Regarding the relationship between thermal properties and electrical conductivity of quartz glass, quartz glass is a kind of high-purity special industrial technical glass containing only a single component of silicon dioxide (SiO2). Because it has a series of special properties that cannot be replaced by other materials, it is very low thermal conductivity, excellent thermal shock resistance, high deformation temperature and softening temperature, very low thermal conductivity, very low dielectric loss and optical transmittance over an extremely broad spectral range from UV to IR. It has played a very important role in modern industry and high-tech fields.
