Polymer Assisted Synthesis and Characterization of Fine ZnWO₄

Abstract:

Zinc tungstate is a scintillator material with excellent photocatalytic and photoluminescent properties. In the present study, fine sized ZnWO4 powders with monoclinic wolframate structure were prepared by chemical precipitation route assisted with polymer evaporation. DTA/TG and XRD were employed to investigate the thermal behaviour and crystallite size evaluation of ZnWO4 .The particle size and morphology of the powder heat treated at different temperature was observed and characterized by SEM. The FTIR spectrum has been used to study the stretching and bending frequencies of the ZnWO4. The result shows that the process provides a technically simple route for the precipitation of fine sized narrow particle distribution and free dense agglomerate ZnWO4 particles.
