O le ā le mea e fa'aaogā i ai le Manganese Dioxide?
*E maua faalenatura le Manganese Dioxide o le minerale pyrolusite, o le puna lea o le manganese ma ana tuufaatasiga uma; E faaaogaina e fai ai le u'amea manganese o se mea e oxidize ai.
*E fa'aaogāina muamua le MnO2 o se vaega o maa mamago: maa alkaline ma le mea ua ta'ua o le sela Leclanché, po'o maa zinc-carbon. Ua fa'aaogāina ma le manuia le Manganese Dioxide o se mea taugofie ma tele mo maa. I le amataga, na fa'aaogāina le MnO2 e maua mai le natura, ona sosoo ai lea ma le manganese dioxide ua faia fa'akemikolo, lea na fa'aleleia atili ai le fa'atinoga o maa Leclanché. Mulimuli ane, na fa'aaogāina le manganese dioxide (EMD) ua saunia fa'akemikolo e sili atu ona lelei, e fa'aleleia atili ai le gafatia o le sela ma le saoasaoa o le saoasaoa.
*O le tele o fa'aaogāga fa'apisinisi e aofia ai le fa'aaogāina o le MnO2 i le faia o keramika ma tioata e fai ma vali e le'o fa'aola. E fa'aaogā i le faia o tioata e aveese ai le lanu lanumeamata e mafua mai i mea leaga o le u'amea. Mo le faia o tioata amethyst, fa'amamāina o tioata, ma valiina o le porcelain, faience, ma majolica;
*O le mea na fa'aputuina o le MnO2 e fa'aaogaina i tekinolosi eletise, pigments, paelo fana enaena, e fai ma mea fa'amago mo vali ma varnish, ma mo le lolomiina ma le valiina o ie;
*E fa'aaogaina fo'i le MnO2 o se pigment ma o se mea e fa'amuamua ai isi manganese compounds, e pei o le KMnO4. E fa'aaogaina o se reagent i le organic synthesis, mo se fa'ata'ita'iga, mo le oxidation o allylic alcohols.
*E faʻaaogaina foʻi le MnO2 i galuega e togafitia ai le vai.
