Reactivity of ZnSb2O6 with ZnTa2O6 and some properties of new limited ZnSb2-xTaxO6 solid solution with tri-rutile structure

Abstract The results obtained within this work have shown the formation of a limited substitutional solid solution with tri-rutile type structure and with the general formula ZnSb 2-x Ta x O 6 in the ZnSb 2 O 6 –ZnTa 2 O 6 system. In the new solid solution Ta 5+ ions are incorporated into the ZnSb 2 O 6 lattice instead of Sb 5+ . The homogeneity range of the new solid solution is for 0  x  ≤ 1.6. The new phase has been characterized by XRD, DTA–TGA, IR and UV–vis methods and its thermal stability has been determined.
