“…In a similar PLZT material, Sn 4+ substitution leads to the narrowing of the hysteresis loop and shifts T m toward lower temperatures. The properties of PLZST single crystals are described in 10 and [11][12][13] Ceramic samples were obtained using a conventional ceramic technology from oxides and carbonates, that is, PbO, ZrO 2 , TiO 2, SnO 2 , and BaCO 3 . After weighing, the components were mixed for 15 h in ethyl alcohol using a FRITSCH ball mill.…”

This paper presents the results of preparing and investigating the solid solution of lead barium zirconate titanate stannate (Pb1−xBax)[(Zr1−yTiy)1−zSnz]O3 with x = 0.25, y = 0.35 and z = 0.00, 0.02, 0.04, 0.08, 0.10. Ceramic samples were obtained from oxides and carbonates using conventional ceramic technology and pressureless sintering. The results of Energy‐dispersive X‐ray spectroscopy (EDS) investigations, XRD studies, as well as dielectric measurements and electromechanical investigations are presented. It was stated that at the room temperature, the structure of the investigated samples is pseudo‐cubic, typical for relaxors. Maximal value of elementary cell parameter is observed for z = 0.02, and for higher values of z, we observe almost linear decrease with increasing z. It was found that with increasing content of the Sn, the temperature Tm at which dielectric permittivity reaches its maximum decreases. Analyzing P‐E hysteresis loops it was stated that the phase transition in the investigated samples takes place at temperatures approximately 100°C lower than the temperature of the dielectric permittivity maximum. The temperature of phase transition was calculated also from hysteresis loops and compared with that obtained from measurements of dielectric permittivity.

“…For practical uses it is important the possibility of controlling parameters of such a type materials as a result of isovalence, or heterovalence substitutions of other ions in A or B positions of the perovskite structures. In recent years there have appeared works about properties of PLZST solid solutions obtained both in the form of monocrystals [6], and ceramics obtained by various methods [7][8][9]. The tin admixture added to such solutions causes, among others, change in the hysteresis loop appearance, which is important taking into account practical uses, for example in high energy impulse capacitors.…”

In this work, the ceramics with the general formula of Pb 0.75 Ba 0.25 (Zr 0.65 Ti 0.35 ) 1-z Sn z O 3 (PBZST) for a constant x = 0.25, constant y = 0.35 and variable z = 0, 0.02, 0.04, 0.06, 0.08, 0.10 were obtained and examined. Powders synthesis was carried out using calcination method in conditions of: T calc = 850 • C/t calc = 3 h, and densification using free sintering method in conditions of: T s = 1250 • C/t s = 4h. For the obtained samples of PBZT and PBZTS ceramics, the microstructure and basic dielectric properties in the frequency function tests were performed.The PBZTS ceramics with relaxor properties is an interesting material to use in the modern electrical engineering, for instance as electrostriction transducers, sensors, or pulse capacitors.
