抄録

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, Nd_1−xMnO_3−y was synthesized by firing the coprecipitate in air without flowing. For the products of Nd_1&minusxMnO_3−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.
