Abstract

Polycrystalline spherical Bi0.5Na0.5TiO3 (BNT) particles with narrow size distributions were obtained by the gel-sol method, where the precursory gel was composed of BiX3 (X = OH, NO3), NaOH, and stable Ti4+ complex which was prepared by mixing Ti(i-C3H7O)4 with triethanolamine to inhibit the uncontrolled hydrolysis in aqueous solution. The resulting morphology was readily controlled as single-crystalline rod-like and tubular shapes with the simple tuning of the Bi/Ti molar ratios in the presence of NaClO4.
