Perovskite oxides MTiO3 (M = Ba, Sr and Ca) with various phase, size, and shape were systematically prepared by solvothermal method in H 2O/glycols mixed solutions. Shape control of the BaTiO3 and SrTiO3 particles was achieved by choice of glycols, and anisotropic rodshaped fine BaTiO3 particles with a tetragonal crystal system were selectively synthesized by use of ethylene glycol. On the other hand, cubicand spherical-shaped BaTiO3 particles were also obtained in H2O and H2O/diethylene glycol systems. These BaTiO 3 particles had a cubic crystal system. Meanwhile, concave cubic-shaped CaTiO3 particles with an orthorhombic phase were synthesized. In our method, triethanolaminetitanium complex was used as the titanium source of MTiO3. Both of the specific adsorption of triethanolamine and solvent effect of glycols is the competitive factor for the control of final particle size and shape.
