Abstract

Mn₃O₄ spinel oxide was synthesized precipitating Mn(NO₃)₂ in aqueous solution with NH₄OH. Reactions were performed with a constant molar ratio Mn²⁺:OH ^-=1:2.5 (Mn²⁺ as a limiting reagent), using microwave radiation during the crystallization step and varying the synthesis atmosphere (air or nitrogen). In presence of air a pure Mn₃O₄ spinel structure was obtained whereas if nitrogen was used, a small amount of Mn oxide-hydroxide (hydrohausmannite) was synthesized with Mn₃O ₄.
