It is hard to melt, but easily oxidized. When manganese(IV) oxide is added to hydrogen peroxide, bubbles of oxygen are given off. Archibald FS, Fridovich I.

MANGANESE PROBLEMSThis article, written by the American Ground Water Trust was originally published in THE AMERICAN WELL OWNER, 2002, Number 1]SOLUTIONS TO MANGANESE PROBLEMSManganese (Mn) is very common in soils and sediment. Manganese is essential to iron and steel production. It is absolutely necessary for the activity of several enzymes that must bind a manganese atom before they can function, including superoxide dismutase, an enzyme that protects us from the harmful effects of toxic oxygen radicals. We now report a comprehensive electrochemical characterization of manganese oxide (MnOx) over a wide pH range, and establish MnOx as a functionally stable OER catalyst owing to self-healing, is derived from MnOx redeposition that offsets … manganese(IV) oxide. A series of calcium–manganese oxides (Ca–Mn–O) were prepared through thermal decomposition of carbonate solid–solution precursors and investigated as electrocatalysts for oxygen reduction reaction (ORR). It is a hard metal and is very brittle. It is commonly found with iron as mineral oxide coatings on the surface of soil and rock grains. Manganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute acids. When finely divided, manganese metal burns in air. J Bacteriol. It burns in oxygen to form the oxide Mn 3 O 4 and in nitrogen to form the nitride Mn 3 N 2. The synthesized crystalline Ca–Mn–O compounds, including perovskite-type CaMnO3, layered structured Ca2Mn First-row metals have been a target for the development of oxygen evolution reaction (OER) catalysts because they comprise noncritical elements.
