摘要：

ZnNb2O6 powder was successfully synthesized via hydrothermal method with Nb2O5 and Zn(NO3)(2)center dot 6H(2)O as raw materials and cyclohexane as solvent. Phase composition, morphology, and chemical composition were determined via a combination of XRD, SEM, TEM and EDS techniques. The effects of synthesis temperature and reaction time on phase composition and particle morphology were investigated in this paper. The results showed that fine ZnNb2O6 powders could be obtained at a hydrothermal temperature of 190 degrees C or above under different reaction time. (C) 2011 Elsevier Ltd and Techna Group S.r.l.
