The electrical conductivity of the transparent quartz glass is 10-17-10-16 West / m, the conductivity of the opaque quartz glass is 10-14-3.2 * 10-13 / m, and its value is related to the purity of the quartz glass. Xiamen Yi only special quartz glass dielectric constant at room temperature and 0-106 Hz frequency, the dielectric constant of the transparent quartz glass is 3.70; opaque quartz glass 3.50, elevated temperature, a slight increase in the dielectric constant, after 450oC, dielectric constant increased significantly.

Dielectric loss

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

Chemical properties of acid and alkali resistant quartz glass belongs to acidic materials, except hydrofluoric acid and hot phosphoric acid, to any other acid showed as inert, is the best acid material. At room temperature, alkali and salt on the quartz glass corrosion degree is minimal, so do not rule out using quartz glass in these agents.

About the relationship between thermal conductivity and thermal conductivity of quartz glass, quartz glass is a kind of high purity special industrial technology glass containing only silicon dioxide (SiO2). As with other materials can not be replaced by a series of special properties, as well as very low thermal conductivity rate, and excellent thermal shock resistance, high deformation temperature and softening temperature, low heat conduction ability, and very low dielectric loss from the ultraviolet to the infrared extremely wide spectral range optical permeability. To make it play a very important role in modern industry and high technology field.
