Summary:The results of studies of polyantimonic crystalline acid with the composition of Sb 2 O 5 · 3.2H 2 O using the impedance spectroscopy technique at low temperatures are presented. Dependences of dielectric permittivity, slope of dielectric losses, and electric module are studied in the frequency range of 100 Hz to 2MHz and temperature range of 220–290 K. It is shown that the limiting stage is proton transport through crystal interface. The activation energy of proton conductivity is 50.21 kJ/mol.
