Abstract

The composition dependence of phase transition temperature in (1-x)PbSc_1/2Ta_1/2O₃-xPbHfO₃ (PSTH) ceramics (0 ≤ x ≤ 0. 2) has been investigated by Raman spectra. From the typical phonon mode variations, the PSTH ceramics unambiguously undergoes three structural transformations with increasing the temperature from 82 to 673 K. It was found that the F_2g phonon mode disappears above the Curie temperature. Moreover, the PSTH ceramics exhibited the paraelectric to ferroelectric phase transitions at 287, 293, 313, 320, and 330 K with the composition. The phenomena can be ascribed to the enhanced length of Pb-O-Ta bonds induced by the incorporation of Hf⁴⁺ ions.
