What is the role of the Mn2O3 Powder?
Mn2O3 is Insoluble in water, acetic acid as well as ammonium chloride solution, dissolved in other inorganic acids. Dissolved in cold hydrochloric acid into brown solution, in hot weaken sulfuric acid or focused sulfuric acid into red option, disintegrated into MnO ₂ and manganese nitrate in hot nitric acid, warmed disintegration to Mn3O4 and also launch O ₂. Presexist in α & alpha; -Mn2O3 and also & gamma; -Mn 2 O 3. The & alpha;- type is decayed by heating nitrate, carbonate, or chloride, a hydride of divalent manganese, airborne to 600 ~ 800 ℃; the γ & gamma;- type is prepared by home heating MnO2 in a vacuum cleaner at 500 ℃ for 78 hrs or by γ & gamma;- MnO (OH) dehydration. It has broad usage and also can be used in towel printing and also dyeing procedure; manganese dioxide is a trivalent manganese hydrate called manganese brown, utilized as the dyeing agent for towel; it is additionally the raw material and also intermediate items; it can be effective catalytic oxidation of organic toxins and nitrogen oxides, catalytic natural combining response; can be used as a soft magnetic material precursor; as the raw material for artificial lithium-ion battery electrode product.
