A method is proposed for determination of the thermal diffusion coefficients of mobile ions through the study of ionic thermoelectric power. Ionic Seebeck coefficients and the heats of ion transport have been measured in [Li(Na,K)]₂O‐Nb₂O₅‐P₂O₅ glasses. The mixed alkali effect influence on the thermoelectric power has been reported for the first time in glasses. Soret coefficients have been calculated for all monoalkali glass samples synthesized in this work. Type of the alkali ion and Nb₂O₅ content dependence of the heat of transfer and thermal diffusion coefficient have been analyzed and discussed.
