He aha ka mea e hoʻohana ʻia ai ka Manganese Dioxide?
*Hōʻike kūlohelohe ʻia ka Manganese Dioxide ma ke ʻano he mineral pyrolusite, ʻo ia ke kumu o ka manganese a me kāna mau hui āpau; Hoʻohana ʻia e hana i ke kila manganese ma ke ʻano he oxidizer.
*Hoʻohana nui ʻia ʻo MnO2 ma ke ʻano he ʻāpana o nā pila kelepona maloʻo: nā pila alkaline a me nā mea i kapa ʻia ʻo Leclanché cell, a i ʻole nā pila zinc-carbon. Ua hoʻohana pono ʻia ʻo Manganese Dioxide ma ke ʻano he mea pila kūʻai haʻahaʻa a nui hoʻi. I ka wā mua, ua hoʻohana ʻia ʻo MnO2 kūlohelohe a ukali ʻia e ka manganese dioxide i hana ʻia me ke kemika e hoʻomaikaʻi nui ana i ka hana o nā pila Leclanché. Ma hope mai, ua hoʻopili ʻia ka manganese dioxide (EMD) i hoʻomākaukau ʻia me ka electrochemically i ʻoi aku ka maikaʻi e hoʻonui ana i ka hiki o ke kelepona a me ka hiki ke wikiwiki.
*ʻO ka nui o nā hoʻohana ʻoihana e pili ana i ka hoʻohana ʻana o MnO2 i nā keramika a me ka hana aniani ma ke ʻano he pigment inorganic. Hoʻohana ʻia i ka hana aniani e wehe i ka ʻōmaʻomaʻo i hoʻokumu ʻia e nā haumia hao. No ka hana ʻana i ke aniani amethyst, decolorizing aniani, a me ka pena ʻana ma luna o ka porcelain, faience, a me majolica;
*Hoʻohana ʻia ka MnO2 i hoʻoheheʻe ʻia i nā electrotechnics, nā pigments, nā pahu pū browning, ma ke ʻano he mea maloʻo no nā pena a me nā varnish, a no ka paʻi ʻana a me ka hoʻoluʻu ʻana i nā lole;
*Hoʻohana ʻia ʻo MnO2 ma ke ʻano he pigment a ma ke ʻano he precursor i nā hui manganese ʻē aʻe, e like me KMnO4. Hoʻohana ʻia ia ma ke ʻano he reagent i ka synthesis organik, no ka laʻana, no ka oxidation o nā alcohols allylic.
*Hoʻohana ʻia ʻo MnO2 i nā hana mālama wai.
