Synthesis of ZnNb2O6 powder with rod-like particle morphologies

A ZnNb2O6 powder was synthesized through the molten salt method. The XRD and SEM results indicated that the crystal ZnNb2O6 powder with rod-like particle morphologies could be obtained via this method at temperature of 600 °C, which is significantly lower than that required by solid-state reaction, where a calcining temperature of 800 °C was needed and the obtained ZnNb2O6 particles were equiaxial. The heat treatment temperature scarcely affected the ZnNb2O6 particle morphologies in the molten salt synthesis process.
