The possibility of the formation of high entropy single-phase perovskites using solid-state sintering was investigated. The BaO-SrO-CaO-MgO-PbO-TiO, BaO-SrO-CaO-MgO-PbO-FeO and NaO-KO-CaO-LaO-CeO-TiO oxide systems were investigated. The optimal synthesis temperature is found between 1150 and 1400 °C, at which the microcrystalline single phase with perovskite structure was produced. The morphology, chemical composition, crystal parameters and dielectric properties were studied and compared with that of pure BaTiO. According to the EDX data, the single-phase product has a formula of NaKCaLaCeTiO and a cubic structure.
