摘要：

The paper presents the results of a study of structural, optical and conductive properties of ferroelectric microparticles based on ATiO(x) (A = Ba, Ca, Sr) obtained by solid-phase synthesis. According to the data obtained, as a result of the synthesis microparticles of dendroid form were obtained. During the study, the dependences of the change in the phase composition and crystallographic characteristics on the choice of component A in the structure of a ferroelectric are established. Studies of conductive and optical characteristics of investigated microparticles were conducted. During tests of conductive characteristics of microparticles, the nonlinearity of the current - voltage characteristics was established due to the presence of impurity inclusions in the structure and a high concentration of vacancy and dislocation defects, which have a significant effect on the ballistic nature of charge transfer.
