Some ceramic materials formed by sintering layered green bodies formed the compacted powders of the basic potassium polytitanate and this one modified with Mn compound are produced and investigated. Using impedance spectroscopy, the electrical properties of the resulting multilayer ceramic materials are studied in the range up to 1 MHz. It is recognized that the frequency dependence of the electrical properties of capacitor structures formed by multiple layers of varied highly polarizable dielectrics differs significantly from those obtained with monolayer dielectrics. Possible applications of multilayer ceramic structures with high permittivity as dielectrics and electrochemically active materials are analyzed.
