Controlled synthesis of CaMoO4 and SrMoO4 rods by a simple sonochemical method

Abstract

CaMoO4 and SrMoO4 rods have been controllably synthesized by a simple sonochemical method without any surfactants at room temperature. The as-prepared powders were characterized by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM). It was found that the ultrasonic time and Na2MoO4 and M(NO3) 2 (M=Ca and Sr) molar ratio played a crucial role on the controllable synthesis of CaMoO4 and SrMoO4 rods. This route is proved to be convenient, mild and energy-efficient, and can be extended to the controllable synthesis of tungstates. © 2012 The Ceramic Society of Japan.
