Abstract : Many desirable features can be brought in when certain ferroelectric materials are doped with calculated amount of foreign atoms. Ba1−2xCaxSrxTiO3 (BCST), Ba0.8Ca0.2TiO3 (BCT) and Ba0.8Sr0.2TiO3 (BST) have been synthesized via Pechini precursor route. It has been found that single phase was formed at 820–860 °C, which was confirmed by the {XRD} analysis. {FTIR} studies confirmed the presence of functional groups such as O–H, carboxylate ester and the carbonate in dry samples. Crystallite sizes of these ceramics were calculated by X-ray line broadening analysis, which were also confirmed by {SEM} studies. {EDX} studies confirmed the high purity of the synthesized materials.
