He aha ka mea e hoʻohana ai i ka Manganese Dioxide?
*Makemake ʻia ʻo Manganese Dioxide ma ke ʻano he mineral pyrolusite, ʻo ia ke kumu o ka manganese a me kāna mau pūhui a pau;Hoʻohana ʻia e hana i ke kila manganese ma ke ʻano he oxidizer.
*Hoʻohana mua ʻia ʻo MnO2 ma ke ʻano he ʻāpana o nā ʻokoʻa kelepona maloʻo: nā ʻāpana alkaline a me ka mea i kapa ʻia ʻo Leclanché cell, a i ʻole nā battery zinc–carbon.Ua hoʻohana maikaʻi ʻia ʻo Manganese Dioxide ma ke ʻano he mea kūʻai ʻole a nui loa.I ka hoʻomaka ʻana, ua hoʻohana ʻia ka MnO2 kūlohelohe a ukali ʻia e ka manganese dioxide i hoʻohuihui ʻia me ka hoʻomaikaʻi nui ʻana i ka hana o nā pihi Leclanché.Ma hope mai, ua hoʻohana ʻia ka manganese dioxide (EMD) i hoʻomākaukau ʻia i ka electrochemically e hoʻonui i ka hiki o ke kelepona a me ka hiki ke helu.
* Nui nā hoʻohana ʻenehana i ka hoʻohana ʻana i ka MnO2 i nā seramika a me ka hana aniani e like me ka puaʻa inorganic.Hoʻohana ʻia i ka hana aniani e wehe i ka ʻōmaʻomaʻo i hana ʻia e nā haumia hao.No ka hana ʻana i ke aniani ʻamethyst, ke aniani hoʻomaʻemaʻe, a me ka pena ʻana ma luna o ka porcelain, faience, a me ka majolica;
* Hoʻohana ʻia ka ea o MnO2 i nā ʻenehana electrotechnics, pigments, browning gun barrels, i mea maloʻo no nā pena a me nā varnish, a no ka paʻi ʻana a me ke kala ʻana i nā lole;
* Hoʻohana pū ʻia ka MnO2 ma ke ʻano he puaʻa a ma ke ʻano he mea mua i nā pūhui manganese ʻē aʻe, e like me KMnO4.Hoʻohana ʻia ʻo ia ma ke ʻano he reagent i ka synthesis organik, no ka laʻana, no ka hoʻohemo ʻana o nā alkohol allylic.
* Hoʻohana pū ʻia ʻo MnO2 i nā noi mālama wai.
