| Popis: | Incorporation of Te and Gd were done based on the stoicheometric formula PbTi[Formula: see text] Te[Formula: see text]GdxO3 (PTTeG). TG characterization of green powder revealed the completion of solid state reaction at temperature 450∘ C. XRD of modified PTTeG powders milled for 10[Formula: see text]h was found most suitable as it gives pure single-phase tetragonal structure. Dielectric constant was found as 2543 at curie temperature of 480∘C in the case of 5[Formula: see text]wt.% of Gd in PTTeG. Piezoelectric Coefficient was found as 241 [Formula: see text] 10 [Formula: see text] C/N at 39[Formula: see text]Kv/cm of poling field. The results obtained were comparable and even better than so far reported in similar kind of materials. |
