A gel was formed when an aqueous solution of BaCl 2 , SrCl 2 , NbF 5 and citric acid in stoichiometric ratio is heated on a water bath. This gel on decomposition at 700°C yielded the nanocrystallites of ternary oxide, Sr 0.5 Ba 0.5 Nb 2 O 6 (SBN) as confirmed by X-ray diffraction study (XRD). Particle size and morphology was studied by transmission electron spectroscopy (TEM). The room temperature dielectric constant at 1kHz is 1000. The ferroelectric hysteresis loop parameters of these samples were also studied by a home built Sawyer–Tower circuit.
