Maxaa loo isticmaalaa Manganese Dioxide?
*Manganese Dioxide wuxuu si dabiici ah ugu dhacaa pyrolusite-ka macdanta, kaas oo ah isha manganese iyo dhammaan isku-dhafka; Waxaa loo isticmaalaa in lagu sameeyo birta manganese sidii oksaydheeye.
*MnO2 waxaa inta badan loo isticmaalaa qayb ka mid ah baytariyada unugyada qalalan: baytariyada alkaline iyo waxa loogu yeero unugga Leclanché, ama baytariyada zinc-kaarboon. Manganese Dioxide waxaa si guul leh loogu isticmaalay sidii walxo baytari oo jaban oo badan. Bilowgii, MnO2 dabiici ah ayaa la isticmaalay ka dibna waxaa la isticmaalay manganese dioxide oo kiimiko ahaan loo sameeyay oo si weyn u hagaajiyay waxqabadka baytariyada Leclanché. Dabadeed, manganese dioxide oo si elektaroonik ah loo diyaariyey (EMD) ayaa la isticmaalay iyadoo la xoojinayo awoodda unugyada iyo awoodda heerka.
*Isticmaal badan oo warshadeed waxaa ka mid ah isticmaalka MnO2 ee dhoobada iyo sameynta galaaska oo ah midab aan dabiici ahayn. Waxaa loo isticmaalaa sameynta galaaska si looga saaro midabka cagaaran ee ay keento wasakhda birta. Waxaa loo isticmaalaa sameynta galaaska amethyst, qurxinta galaaska, iyo rinjiyeynta foornada, faience, iyo majolica;
*Digaaca MnO2 waxaa loo isticmaalaa farsamada korontada, midabyada, foosto qoriga lagu qalajiyo, sida qalajiyaha rinjiga iyo varnish-ka, iyo daabacaadda iyo rinjiyeynta dharka;
*MnO2 waxaa sidoo kale loo isticmaalaa midab ahaan iyo horudhac u ah isku-dhafka kale ee manganese, sida KMnO4. Waxaa loo isticmaalaa sidii fal-celin ku jirta isku-darka dabiiciga ah, tusaale ahaan, oksaydheynta alkoholka allylic.
*MnO2 waxaa sidoo kale loo isticmaalaa codsiyada daaweynta biyaha.
