Abstract
Single-phase manganese oxide particles having a wurtzite crystal structure. The particles can be obtained by thermally decomposing a compound containing manganese. In this procedure, a reducing agent consisting of at least one of a polyol-based material and an ethylene glycol stearate-based material is added as an additive to the reaction system. It is heated at a first temperature (200° C. or lower) under a reduced pressure atmosphere, then the temperature is raised, and the product is heated at a temperature higher than the first temperature under an inert gas atmosphere.
