Manganese dioxide e sebelisetsoa eng?
*Manganese Dioxide e hlaha ka tlhaho e le mineral pyrolusite, e leng mohloli oa manganese le metsoako eohle ea eona; E sebelisoa ho etsa tšepe ea manganese joalo ka oxidizer.
*MnO2 e sebelisoa haholo-holo e le karolo ea libeteri tsa lisele tse omeletseng: libeteri tsa alkaline le seo ho thoeng ke Leclanché cell, kapa libeteri tsa zinc-carbon. Manganese Dioxide e 'nile ea sebelisoa ka katleho e le lisebelisoa tsa betri tse theko e tlaase le tse ngata. Qalong, MnO2 ea tlhaho e ne e sebelisoa e lateloa ke manganese dioxide e entsoeng ka lik'hemik'hale e ntlafatsang haholo ts'ebetso ea libeteri tsa Leclanché. Hamorao, ho ile ha sebelisoa manganese dioxide (EMD) e sebetsang hantle ka ho fetisisa ea electrochemically, e matlafatsang matla a lisele le bokhoni ba sekhahla.
* Litšebeliso tse ngata tsa indasteri li kenyelletsa ts'ebeliso ea MnO2 ka lirafshoa le ho etsa likhalase joalo ka pigment ea inorganic. Se sebedisoang ha ho etsoa likhalase ho tlosa botala bo botala bo bakoang ke litšila tsa tšepe. Bakeng sa ho etsa khalase ea amethyst, khalase e senyang mebala, le ho penta holim'a porcelain, faience le majolica;
*The precipitate of MnO2 e sebelisoa electrotechnics, pigments, browning gun barrel, as dryer for paint and varnishes, and for printing and daye textile;
*MnO2 e boetse e sebelisoa e le pigment hape e le selelekela sa metsoako e meng ea manganese, joalo ka KMnO4. E sebelisoa e le reagent ho organic synthesis, mohlala, bakeng sa oxidation ea allic alcohols.
