| Popis: | Incorporation of Se and Sm were done based on the stoichiometric formula PbTi0.8−xSe0.2SmxO3 (PTSeS). TG characterization of green powder revealed the completion of solid state reaction at temperature 450 °C. XRD of modified PTSeS powders milled for 10 h was found most suitable as it gives pure single phase tetragonal structure. Dielectric constant was found as 2700 at curie temperature of 470 °C in the case of 5 wt percent of Sm in PTSeS. Piezoelectric coefficient was found as 230 × 10 − 12 C/N at 35 Kv/cm of poling field. The results obtained were comparable and even better than so far reported in similar kind of materials. |
