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&minusxMnO3−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.
