• Electrical behavior of alkaline-earth oxides in V–Mo tellurite glasses was studied.
• The electric formalisms show a weak charge carrier interaction among bivalent cations.
• Modifier cation radii and its electrical behavior do not show a straight relationship.
• Bivalent cations on tellurite glasses are poor candidates as ionic conductors.
Electrical response changes due to the incorporation of alkaline-earth oxides in the vanadium–molybdenum tellurite glassy matrix have been studied. The results are explained by analyzing the electric formalisms representations. A non-straightforward relationship to the modifier oxide ionic radius was found and the results suggest poor charge carrier interactions even at high alkaline-earth concentrations. The electrical behavior of the studied materials gives strong evidence that alkaline-earth modified tellurite glasses are poor candidates to become good ionic glassy conductors.
