In this paper, MTiO 3 (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 SrTiO 3 , dodecahedral BaTiO 3 , and cross-shaped CaTiO 3 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 MTiO 3 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 MTiO 3 perovskites, but also facilitates the study of potential applications of titanate perovskite compounds. MTiO 3 (M = Sr, Ba, and Ca) perovskite polyhedra have been successfully synthesized through a facile hydrothermal route with the stick-like titania as precursor.
