Summary:A study of cobalt doping effect on the dielectric response and elastic properties of Ba 0.95 Pb 0.05 TiO 3 solid solution within the range of 20-200 °C is reported. The results of a study of the dielectric permittivity, dielectric loss and elastic parameters in the samples of ceramic Ba 0.95 Pb 0.05 TiO 3 +xCo 2 O 3 in the range of ferroelectric phase transition are presented. Modifying by admixture of Co is found to change the thermal anomalies of elastic and dielectric properties substantially, as well as to shift the ferroelectric phase transition temperature.
