    Abstract

    The coprecipitate of carbonates was obtained by titrating an ammonium carbonate solution into an hydrochloric solution of MnO2 and Nd2O3. The non-stoichiometric perovskite-type oxide, Nd1-xMnO3-y was synthesized by firing the coprecipitate in air without flowing. For the products of Nd1-xMnO3-y prepared at 1100 °C, the single phase showing the stable y/x value 1.5 was obtained in the x=0.05 to 0.20 region, and a by-product Mn3O4 was appeared in x=0.25.
