Electrical Conductivity, Dielectric, Modulus and Optical Studies of Ag₂SO₄ and TiO₂ Composite Solid Electrolytes

Abstract:

Composite solid electrolytes of the molecular formula (1-x) Ag₂SO₄ and x TiO₂ have been prepared by solid state reaction method. The prepared materials were characterized by various techniques such as X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric-diffrential thermal analysis (TG-DTA) and scanning electron microscopy (SEM). A sharp increase of conductivity was found in the Arrhenius plot at 693 K due to the β →α phase transition, which is slowed down with the addition of TiO₂ particles. The composition x=0.3 shows the maximum conductivity σ = 12.31 S cm^-1 at 500 °C. The temperature dependent modulus values involve single type of conduction mechanism over the entire range of temperatures. The optical band gap energy for the pure Ag₂SO₄ is found to be 4.79 eV, which has decreased with the amount of TiO₂ contents because of the defects and changes in local lattice symmetry of the composites.
