Abstract
Incorporation of Te and Sm were done based on the stoicheometric formula PbTi0.8-xTb0.2SmxO3 ( PTTbS). TG characterization of green powder revealed the completion of solid state reaction at temperature 4500 C. XRD of modified PTTbS powders milled for 10 hours was found most suitable as it gives pure single phase tetragonal structure. Dielectric constant was found as 2632 at curie temperature of 4800 C in the case of 5 wt percent of Sm in PTTbS . Piezoelectric Cooefficient was found as 211 x 10 -12 C/N at 39 Kv/cm of poling field.The results obtained were comparable and even better than so far reported in similar kind of materials.
