Chii chinonzi manganese dioxide inoshandiswa?
* Manganese Dioxide inoitika nechisikigo seye mineral Pyrolusite, inova tsime remanganese uye makomendi ayo ese; Yaishandiswa kugadzira manganse simbi se oxidizer.
* MNO2 inonyanya kushandiswa sechikamu chemabhatiri akaoma emari: Alkaline mabhatiri uye inonzi Leclanché cell, kana zinc-carbon mabhatiri. Manganese Dioxide yakashandiswa zvinobudirira seinodhura uye yakawanda bhatiri zvinhu. Pakutanga, zvomuzvarirwo kuitika Gare gare, iyo yakanyanya kunaka elecrochemicy yakagadzirirwa Manganese Dioxide (EMD) yakaiswa kuisazve cell kugona uye chiyero kugona.
* Akawanda maindasitiri anoshandisa anosanganisira kushandiswa kweMNO2 mune ceramics uye girazi-kugadzira seyakarongeka pigment. Inoshandiswa mune girazi yekubvisa iyo girini tint inokonzerwa nekusvibiswa kwesimbi. Kugadzira maAmethyst girazi, girazi rekushongedza, uye pendi paPorcelain, mwoyo murefu, neMaMaolica;
* Iyo yekufungidzira yeMNO2 inoshandiswa mumagetsi, pigment, browning pfuti mbiya, sekuoma kwekupenda nehuranda, uye nekudhinda uye nekudhinda uye nedhiri.
* MNO2 inoshandiswawo se pigment uye sepamberi kune mamwe madzishe emanganese, senge Kmno4. Iyo inoshandiswa seyakagadzirisirwa mu organic syntic synthesis, semuenzaniso, nekuda kwekunhonga kweallonehols.
* MNO2 inoshandiswawo muzvishandiswa mvura zvekurapa.
