Influence of Synthesis Temperature on the ZnNb2O6 Powders Prepared via Co-Precipitation Method
Abstract:
ZnNb2O6 powder was successfully synthesized via coprecipitation method with Nb2O5、Zn(NO3)2·6H2O as raw materials and ammonia as precipitant agent. This precursor on heating at750°C, produced ZN powders. Phase composition, morphology and chemical composition were studied via a combination of XRD, TEM and EDS technique. The effects of synthesis temperature on phase composition and particle morphology were investigated in this paper. The results showed that with the increase of the synthesis temperature, the particle size decreases. We could get the ZnNb2O6 powder with high purity, fine crystalline when the synthesis temperature is at 50°C.
