mixture with the same stoichiometry. However, when pH>5.0, the coprecipitation process of nickel ions, cobalt ions and oxalate ions is a fractional precipitation process, and the obtained coprecipitate is a complex mixture with uniform component distribution, not a single-phase solid solution. Key words: Ni-Co oxalate; solid solution; coprecipitates; fractional precipitation; mechanical mixtures 镍钴......
