MnO, ore, Mn,O, and Mn,O, were reduced In a thermobalance at various hydrogen partial pressures and m the temperature range 275400ยฐC It was found that the MnO, ore and Mn,O, are both reduced stepwise via Mn,O, Two models were tried to describe the reactions, the shrmkmg core model and a more recentl

The reduction of colloidal MnO(2) by Mn(2+) in aqueous HClO(4) has been studied by a spectrophotometric method. The reaction product is Mn(III). The reaction is of first order in both colloidal MnO(2) and H(+), whereas it presents a fractional order (0.58+/-0.02) in Mn(2+). The reaction is retarded
