Abstract
Alkali metal iron (IV) and iron (VI) ferrates are produced by forming a particulate mixture of reactants including an alkali metal nitrogen oxygen compound and an iron material selected from the group of iron oxide, Fe.sub.2 O.sub.3, Fe.sub.3 O.sub.4 and an iron compound which self-reacts at a temperature less than about 1100.degree. C. to form Fe.sub.2 O.sub.3. The mixture of reactants is subjected to a predetermined elevated temperature for a predetermined time duration sufficient to bring about a reaction between the reactants which produces at least one of iron (IV) and iron (VI) ferrates. The molar ratio of alkali metal nitrogen oxygen compound to the iron material is preferably in the range extending between about 4:1 and about 8:1.
