Dioxide ya Manganese ikoreshwa iki?
* Dioxyde ya Manganese ibaho bisanzwe nka minerval pyrolusite, niyo soko ya manganese hamwe nibiyigize byose;Ikoreshwa mugukora ibyuma bya manganese nka okiside.
* MnO2 ikoreshwa cyane cyane nkigice cya bateri yumye: bateri ya alkaline nicyo bita selile Leclanché, cyangwa bateri ya zinc - karubone.Dioxyde ya Manganese yakoreshejwe neza nkibikoresho bya batiri bihendutse kandi byinshi.Mu ikubitiro, MnO2 isanzwe iboneka yakurikiwe na dioxyde de manganese ya chimique ikomatanya cyane imikorere ya bateri ya Leclanché.Nyuma, hashyizweho ingufu za mashanyarazi ya dioxyde de manganese (EMD) yakoreshejwe neza yongerera ubushobozi selile nubushobozi bwibipimo.
* Inganda nyinshi zikoreshwa mu nganda zirimo gukoresha MnO2 mu bukerarugendo no gukora ibirahuri nka pigment idasanzwe.Ikoreshwa mugukora ibirahure kugirango ikureho icyatsi kibisi cyatewe numwanda wicyuma.Mugukora ibirahuri bya amethyst, gushushanya ibirahuri, no gushushanya kuri farufari, faience, na majolika;
* Imvura ya MnO2 ikoreshwa muri electrotechnics, pigment, ingunguru yimbunda yimbunda, nkumisha kumarangi na langi, no gucapa no gusiga imyenda;
* MnO2 nayo ikoreshwa nka pigment kandi nkibibanziriza ibindi bikoresho bya manganese, nka KMnO4.Ikoreshwa nka reagent muri synthesis organique, kurugero, kuri okiside ya allylic alcool.
* MnO2 nayo ikoreshwa mugukoresha amazi.
