“…The comparison of the χ″( T ) dependences at a temperature far above Curie temperatures, where electric conductivity is the main contribution to dielectric loss, clearly evidenced the fact that PFT ceramics exhibit smaller electric conductivity than the PFN ones. This feature follows the rule that tantalate analogues of niobates of the complex perovskites Pb(B’,B”)O 3 are characterized by a smaller electric conductivity …”

“…Sb 2 O 5 and manganese carbonate or manganese acetate tetrahydrate were heated in the melt at 900 °C for 3 h, before cooling at 1.5 °C per hour to 700 °C, at which point the molten flux was poured out on a steel plate and washed away with dilute HCl. Crystals of PbYb 0.5 M 0.5 O 3 (M=Nb, Ta) and PbMg 0.5 W 0.5 O 3 136 were successfully grown with a flux of PbO‐PbF 2 ‐B 2 O 3 with a maximum soak temperature of 1200 °C. During the cooling of the reactions, molten flux was decanted at 880 °C, and following cooling to room temperature, any remaining solidified flux was washed away in hot acetic acid and dilute nitric acid, which yielded octahedral crystals (Figure 29) up to 6 mm in size.…”

“…At T c approximately equal to 573 K both compounds undergo first order phase transition from the cubic (Fm3m) paraelectric phase (PE) to the orthorhombic (Pbnm) antiferroelectric (AFE) phase [8][9][10][11][12]. In PYT the second transition from the antiferroelectric phase to the ferroelectric phase (FE) occurs at about 450 K [9,13]. Knowledge of the structural and dielectric properties of such compounds allows us to tailor the physical properties of designed solid solutions systems.…”
