Popis:	We present the results of preparation and investigation of antiferroelectric/relaxor/paraelectric (AFE/RFE/PE) phase transitions in ceramics, (Pb0.88Ba0.1La0.02)(Zr0.6Sn0.4− x Ti x )0.995O3 with x = 0.05, 0.055, 0.06, and 0.065, obtained from oxides and carbonates using a conventional ceramic technology. Such compositions can be good candidates for energy storage in pulse capacitors. For such application, the critical field should be appropriate, i.e., neither too high nor too low, since the transition from AFE to FE/RFE properties should take place in fields close to electric breakdown, since in such situation the stored energy is the biggest. We present the results of investigations of the microstructure, dielectric permittivity, and P–E hysteresis loops at various temperatures. It has been stated that some of the investigated materials exhibit field-induced AFE/FE or AFE/RF transition appropriate for application in pulse capacitors.
