Abstract
Polyantimonic acid with the composition Sb2O5 · 2H2O has been studied by impedance spectroscopy. Its dielectric permittivity, dielectric loss tangent, electric modulus, and impedance have been determined in a wide frequency range, from 10 to 2 × 106 Hz, at temperatures from 370 to 480 K. The results demonstrate that proton transport is brought about by hopping between water molecules and oxygens and is limited by grain boundaries. The activation energy for proton conduction is 42 kJ/mol.
