بيت /manganese dioxide reduction kiln
Manganous oxide is made by the reduction of manganous dioxide (MnO 2) by carbon, hydrogen, carbon monoxide, or hydrocarbons at temperatures between 400 and 800 °C (750 and 1,450 °F). Manganese is readily assimilated by plants in this form, so that MnO is used as a fertilizer supplement in manganesedeficient regions.

• Avoid very heavy reduction followed by periods of oxidation. • It is best to start reduction one or two cones higher than the bisque temperature, this period in the glaze kiln can oxidize any remaining potential 'blister producing' volatiles that the bisque did not take care of.

In a classical laboratory demonstration, heating a mixture of potassium chlorate and manganese dioxide produces oxygen gas. Manganese dioxide also catalyses the decomposition of hydrogen peroxide to oxygen and water: 2 H 2 O 2 → 2 H 2 O + O 2. Manganese dioxide decomposes above about 530 °C to manganese(III) oxide and oxygen.

Reduction of manganese dioxide is demonstrated for an in vitro ferrireductase system that includes NADPHdependent ferrireductase and the ironbinding compound (IBC) isolated from the whiterot fungus Phanerochaete sordida YK624. The Fe(II)–IBC complex was more effective in reducing manganese dioxide to Mn(II) than were complexes of Fe(II) and organic acids of low molecular weight such as .

The selective catalytic reduction of NOx (NO + NO2) at low temperature with ammonia has been investigated with natural manganese ore, pure manganese dioxide, and manganese dioxide supported alumina. The catalysts showed high activities for NOx reduction with NH3 in the presence of O2 at temperatures below 250 °C. The decrease of SCR activity without oxygen in the gas phase .
