Synthesis of ZnTa2O6 from peroxide solutions

We have studied the formation of zinc metatantalate from peroxide solutions. The results indicate that the use of peroxide solutions enables stoichiometric ZnTa2O6 to be prepared. The crystal structure of the low-temperature phase of ZnTa2O6 forms at a calcination temperature of 700A degrees C. The synthesized ZnTa2O6 powders have been characterized by X-ray diffraction, differential thermal analysis, thermogravimetry, and scanning electron microscopy.
