Electrical conductiviry of solid and molten lithium sulfate

Abstract

The electrical conductivity of lithium sulfate has been measured over the temperature range 575-970 °C. It is found that Ahehenius equations fit the experimental data slightly less well than empirical relations, such as [formula omitted] and [formula omitted] (t in degr. C). Due to the similarity in transport properties between cubic Li2SO4 and molten salts, comparisons with ionic melts are made in the discussion of our results. The ratio between the conductivity and the cation Selfdiffusion coefficient is less than required by the Nernst-Einstein relation, which indicates that rotation or ring mechanisms are of importance for diffusion in cubic Li2SO4. © 1965, Walter de Gruyter.
