Abstract
A production process for composite oxide expressed by a compositional formula: LiMnAO, where 'A' is one or more kinds of metallic elements other than Mn; and 0≦'x'<1, obtained by preparing a raw-material mixture by mixing a metallic-compound raw material and a molten-salt raw material with each other, the metallic-compound raw material at least including an Mn-containing nitrate that includes one or more kinds of metallic elements in which Mn is essential, the molten-salt raw material including lithium hydroxide and lithium nitrate, and exhibiting a proportion of the lithium nitrate with respect to the lithium hydroxide (Lithium Nitrate/Lithium Hydroxide) that falls in a range of from 1 or more to 3 or less by molar ratio; reacting the raw-material mixture at 500° C. or less by melting it; and recovering the composite oxide being generated from the raw-material mixture that has undergone the reaction.
