Abstract

Strontium titanate (SrTiO3) powder has been prepared through a liquid-phase precursor (LPP) method involving strontium (Sr) acetate and different types of titanium (Ti) raw materials; the powders were synthesized using two kinds of lactate complex and TiCl3. The effects from the addition of the Ti raw materials to the nanostructure and the resultant synthetic efficiency were investigated in this work for the development of nano-sized particles and a low firing temperature. The morphology and size of the SrTiO3 nanopowders were controlled by adjusting the Sr- and Ti-precursor concentrations and the selection of the type of Ti raw material. The most-effective raw material was selected and then used as the basis for the attainment of the results in accordance with the ratio. Using X-ray diffraction (XRD), phase analyses of the samples calcined at different temperatures and compositions were performed. SEM was used for the characterization of the morphologies of the raw materials and reaction products, and they varied from ∼25 nm to ∼50 nm.
