The motivation guidelines for the development of new high-temperature wide operational range dielectrics are given. Afterwards, the fundamental physics of dielectricity are described, followed by a brief general description of ferroelectricity and piezoelectricity. Moreover, the material detailed requirements for high-temperature dielectrics are given and a literature review of materials with suitable properties for high-temperature capacitors is presented. Regarding the experimental part, lead-free high-temperature dielectrics in the Bi0.5Na0.5TiO3-BaTiO3 and Bi0.5Na0.5TiO3-BaTiO3-K0.5Na0.5NbO3 systems doped with different concentrations of CaZrO3 were synthesized. Their structural, microstructural and electrical properties were characterized.
