Conductivity and chemical properties of quartz window sheet

The quartz window sheet has very low thermal conductivity, excellent thermal shock resistance, high deformation temperature and softening temperature, low thermal conductivity, low dielectric loss and optical transmittance in a very wide spectral range from ultraviolet to infrared.

Quartz window slice – conductivity

The conductivity of transparent quartz window slice is 10-17-10-16 W/m, and that of opaque quartz window slice is 10-14-3.2 × 10-13 W/m, its value is related to the purity of the quartz window slice. At room temperature and 0-106 Hz, the dielectric constant of transparent quartz window is 3.70; The dielectric constant of the opaque quartz window is slightly increased with the increase of temperature, and after 450oC, the dielectric constant is significantly increased.

Dielectric loss The relationship between the dielectric loss of the quartz window and the temperature is that the dielectric loss increases with the increase of the temperature, and above 350oC, the dielectric loss increases more obviously with the increase of the temperature.

Quartz window slice – chemical property

Quartz is an acid material, which is inert to any other acid except hydrofluoric acid and hot phosphoric acid, and is a good acid-resistant material. At normal temperature, alkali and salt have very little corrosion on quartz glass, so it is not excluded to use quartz in these reagents.

As for the relationship between the chemical properties and conductivity of the quartz window sheet, the quartz window sheet is a kind of high-purity special industrial technical glass containing only silicon dioxide (SiO2). Because it has a series of special properties that cannot be replaced by other materials, such as 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 in a very wide spectral range from ultraviolet to infrared.
