In this paper, MTiO3 (M = Sr, Ba, and Ca) perovskite polyhedra have been successfully synthesized through a facile hydrothermal route, in which appropriate amounts of metal salts and sodium hydroxide are mixed with the stick-like titania powders to fabricate the products. Cubic SrTiO3, dodecahedral BaTiO3, and cross-shaped CaTiO3 perovskites are finally obtained. The experimental conditions have also been investigated in detail and a feasible growth mechanism is proposed to illustrate the formation of MTiO3 perovskites. Furthermore, we demonstrate the possibility of the method, in which titania nanorods act as the precursor, to produce titanate compounds with a unique morphology. This work not only enriches the synthesis methods of MTiO3 perovskites, but also facilitates the study of potential applications of titanate perovskite compounds.
