Abstract

PURPOSE: To provide superior magnetic characteristic by mixing the fine powder of metal oxides of oxidation reduction potential higher than that of metal compounds to the said compounds and heat-treating the mixture.
CONSTITUTION: The oxide fine powder of metals of the oxidation reduction potential higher than that of metal oxides, metal salts of organic acid, etc. to these and the mixture is subjected to vapor-phase reduction at high temperatures. For example, γ-Fe2O3 30g is mixed in an equal amount of copper oxide fine powder and the mixture is reduced for 3 hours in hydrogen gas flow at a temperature of 460°C. Thereby, the sintering among the particles owing to the high-temperature treatment is prevented and the reduction reaction of the entire part of the reaction system is accelerated, whereby the reaction is finished in a short time and the extremely superior magnetic characteristic is given.
