Manganese Oxide — Reduction - NETZSCH Analyzing

Manganese Oxide — Reduction. Manganese oxide (MnO 2) is often used in chemistry as an oxidizer but also, for example, as a cathode material in batteries.The STA measurement shows mass steps at approx. 600°C and 950°C which are due to the reduction of MnO 2 into Mn 2 O 3 and finally into Mn 3 O 4.The values of 9.20% and 3.07% match exactly with the stoichiometrical values thus reflecting
