O le a le mea e fa'aoga ai le Manganese Dioxide?
*Maganese Dioxide e tupu faanatura e pei o le mineral pyrolusite, o le puna lea o le manganese ma ona tuufaatasiga uma;Faʻaaogaina e fai ai le sila manganese e fai ma oxidizer.
*MnO2 o lo'o fa'aaoga muamua e fai ma vaega o ma'a sela mamago: ma'a alkaline ma le mea e ta'ua o le cell Leclanche, po'o ma'a zinc-carbon.O le Manganese Dioxide ua fa'aaogaina lelei e avea ma mea tau maa e taugofie ma tele.I le taimi muamua, na fa'aaogaina le MnO2 fa'alenatura ona soso'o ai lea ma le manganese dioxide fa'amasani ma fa'aleleia atili ai le fa'atinoga o ma'a Leclanché.Mulimuli ane, na faʻaaogaina le manganese dioxide (EMD) sili atu ona lelei e faʻaaogaina eletise e faʻaleleia ai le gafatia o le sela ma le gafatia.
*O le tele o fa'aoga tau alamanuia e aofia ai le fa'aogaina o le MnO2 i sima ma le fai tioata e pei o se pa'u e le fa'aogaina.Fa'aaogaina i le fai tioata e aveese ai le lanu lanumeamata e mafua mai i le u'amea leaga.Mo le faia o le tioata amethyst, tioata fa'alanu, ma le valiina i luga o le porcelain, faience, ma le majolica;
*O le pa'u o le MnO2 o lo'o fa'aaogaina i mea tau eletise, lanu, pa'u fana enaena, e fa'amamago mo vali ma varnishes, ma mo le lolomiina ma le valiina o ie;
*MnO2 o lo'o fa'aogaina fo'i e fai ma pua'a ma fa'amasani i isi fa'afefiloi manganese, pei ole KMnO4.E faʻaaogaina e avea o se reagent i le faʻaogaina o meaola, mo se faʻataʻitaʻiga, mo le faʻamaʻiina o ava malosi.
*O lo'o fa'aogaina fo'i le MnO2 ile fa'aogaina ole vai.
