Abstract

We developed a new synthetic route of water-soluble complexes using TiCl4 and Ti(SO4)2 as starting materials. The yield of Ti and the removal rate of the Cl- ion were over 85 and 98%, respectively. The lactato titanium complex solution obtained by this new synthetic route remained stable for more than 3 months without any precipitation. Single-phase CaTiO3, SrTiO3, and BaTiO 3 were synthesized from the lactato titanium complex by heating at 873K for 5 h. The nano-structured CaTiO3, SrTiO3, and BaTiO3 particle sizes were 50, 30, and 30nm in diameter, respectively, and smaller than those obtained by the solid-state method. We have succeeded in the synthesis of very fine particles of CaTiO3, SrTiO3, and BaTiO3 at a temperature 400K lower than that required for the solid-state method.
