Abstract

Electrical conductivity of Li(Na,K)2O-Nb2O5-P2O5 glasses and glass-forming melts has been measured in a wide temperature range (298-1173 K). Logarithm of the preexponential factor and activation energy of migration have been determined. Mixed alkali effect has been observed in niobophosphate glass-forming melts. Diffusion coefficients for Li+, Na+, and K+ ions have been calculated. The influence of the type of alkali ion and Nb2O5 content on the diffusion coefficients has been determined.
