    • Abstract

       

      Active manganous oxide preparedin situ is mixed in a closed system with a coprecipitated mixture of zinc and ferric oxides, and then heated in an inert atmosphere to 800°C to form the manganous zinc ferrite at this relatively low temperature. A volatilizable binder employed for pressing is first distilled off in an inert atmosphere and the sintering is then carried out in a controlled static atmosphere. The formation of the spinel with total absence of Mn3+ far below the sintering temperature, and the subsequent sintering without any possibility of oxidation of Mn2+ at any stage result in improved properties.
