Abstract :
Ceramic solid solutions on base of 0.36BiScO3 -0.64PbTiO3 compositions doped by additives Bi2O3, Ni2O3, MnO2, and LiF with low melting temperatures were prepared by the solid state reaction method. Phase formation, microstructure and dielectric properties of modified ceramics were studied. Dense single phase samples characterized by the average grain size varied from submicron till tens mm were obtained at lower temperatures. Influence of additives on dielectric properties and on the effects of dielectric relaxation was revealed.
