Electrical transport in the system Li2SO4-mLi2MoO4-2mLi3VO4

Article abstract of DOI:10.1007/BF00575405

The electrical conductivity (σ) and thermoelectric power (S) of three compounds (m = 0, 0.5 and 1) in the system Li₂SO₄-mLi₂moO₄-2mLi₃ VO₄ is reported from 500°C to the melting point. All three solids show a superionic phase just below their melting point. In this phase, σ decreases but activation energy and span of superionic phase increases for compounds with larger m. The phase transition temperature (T_p) from normal to superionic phase decreases with m. Below T_p, the order of σ is reversed. It increases with m but becomes mixed with the dominant ionic part.
