摘要：

LiMnPO4 with controlled morphologies was synthesized in mixed solvents system via changing the ratio of solvents of glycol to water. With the decrease of ratio of glycol to water, shuttles made up of plates, shuttles with sharp two stages, flower-like shuttles and beautiful porous nanowires of LiMnPO4 were obtained in sequence. Dielectric constant and viscosity of solution should be the key causes to influence the morphologies of the final products. The phase purity and composition were verified by X-ray diffraction (XRD), and the microstructure was observed by transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HRTEM). This synthetic method provides us a new idea to obtain new structure materials. (C) 2012 Elsevier B.V. All rights reserved.
