Abstract
Dielectric properties of the crystalline hydrates of mineral salts are studied at 1.11 GHz in the temperature range 20–196°C. It is found that the temperature dependence of the complex permittivity has a non-linear character and can be attributed to changes in the internal structure of crystalline hydrate. Hysteretic behavior of the complex permittivity in the heating-cooling cycle is revealed.
