Results of studying the structure and chemical composition of perovskite phases synthesized by solid-state sintering in multicomponent oxide systems: (Ba,Sr,Ca,Mg,Pb)(Ti,Zr)O3, (Ba,Sr,Ca,Mg,Pb)(Ti,Zr,Hf)O 3 , (Ba, Sr, Ca,Mg,Pb)(Ti,Zr,Hf, Sn)O 3 , and (Ba,Sr,Ca,Mg,Pb)(Ti,Zr,Hf,Sn,Mn)O 3 are presented. The chemical composition of the obtained samples was investigated using a JEOL JSM7001F scanning electron microscope equipped with an Oxford INCA X-max 80 energy-dispersive X-ray fluorescence spectrometer. The structure was studied with a Rigaku Ultima IV powder X-ray diffractometer. It was demonstrated the possibility of obtaining a high-entropy perovskite phase. Elements (Ba, Sr, Ca, Ti, Zr, Hf, Sn), which can form the high-entropy perovskites have been determined, as well as the elements (Pb, Mg, Mn), which, for various reasons, are hardly incorporated in the high-entropy perovskites.
