  • Abstract
    The ternary undecatungstoferroaluminic heteropoly acid H6[Al(H2O)FeW11O39]·14H2O has been prepared by the ion exchange-cooling. The optimal proportion of solutions of the component elements and the pH of the synthesis reaction are given. The product is characterized by chemical analysis, potentiometric titration, IR, UV, XRD and TG-DTA. The results of AC impedance measurement show that its proton conductivity is 4.07×10−4 S cm−1 at room temperature (18 °C).
