Abstract
Preparation of a mono-phase spinel from a ternary system Mn-Co-Ni oxide with a molar ratio of 3.0∶1.9∶1.1 was investigated. It was found that the oxidation profile of a rock salt-type oxide, which was formed at 1400 °C, was the most significant factor. As a result, the perfect mono-phase specimen was obtained by water quenching the rock salt-type oxide and then heat treating to oxidize it for more than 3 h at 1000°C.
