研究了由摩尔比为3.0：1.9：1.1的三元体系Mn-Co-Ni氧化物制备单相尖晶石。研究发现，在1400℃时形成的岩盐型氧化物的氧化剖面是最重要的因素。结果表明，岩盐型氧化物经水冷处理后，在1000℃下热处理3h以上，即可获得理想的单相样品。
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.
