Abstract

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.
