Electric and dielectric properties of (1-x)Pb(Fe2/3W1/3)O3-xPbTiO3 solid solu¬tions were investigated as a function of the frequency and temperature. Dielectric measurements over the temperature showed the presence three contributions, which were related to the ferro-paraelectric phase transition (around 180K) and to conductive contributions (in the range 200K- 700 k). The FE phase transition of Pb(Fe2/3W1/3)O3 (PFW) is shifted to higher temperatures by PbTiO3 (PT) additions. Conductive contributions were associated to an electronic conductivity with activation energy around 0.45 – 0.55 eV.
