The rapid development of telecommunication and information technology aims to design and investigate new functional materials. Glasses in the TeO 2 -BaO-V 2 O 5 seems to be promising materials within this purpose. In this connection the structure and dielectric properties of the glasses have been studied. Small polaron hopping of V 4+ to V 5+ ion in the vanadate chains and the influence of BaO and TeO 2 on the dielectric permittivity, dielectric losses and frequency depended conductivity of the glasses measured at room temperature in the frequency range from 100 Hz to 1 MHz have been discussed.
