Barium Strontium Titanate (BST), with the general formula Ba 1-x Sr x Ti O 3 hold perovskite phase of Tetragonal Tungsten Bronze (TTB) structure was considered as promising lead-free ferroelectric material. DSC, XRD, HRTEM and SEM analysis confirms the calcination temperature, phase purity, particle size and microstructure of the barium strontium titanate ferroelectric materials prepared. Unlike other materials,the BST exhibits ferroelectricity over wide composition range 0.01 ≤ x ≤ 0.30 and 0.20 ≤ x ≤ 0.80, respectively. It delivers an opportunity to design BST based ferroelectric with desired properties to meet the requirements ofdevicefabrication such as phase shifters and voltage-controlled oscillators.
