Menene amfani da Manganese Dioxide?
*Manganese Dioxide yana samuwa ta halitta a matsayin pyrolusite na ma'adinai, wanda shine tushen manganese da dukkan mahaɗansa; Ana amfani da shi don yin ƙarfe na manganese a matsayin mai hana oxidation.
*Ana amfani da MnO2 a matsayin wani ɓangare na batirin busassun ƙwayoyin halitta: batirin alkaline da abin da ake kira Leclanché cell, ko batirin zinc-carbon. An yi amfani da Manganese Dioxide cikin nasara a matsayin kayan batiri mai araha da wadata. Da farko, an yi amfani da MnO2 na halitta ta hanyar halitta sannan aka haɗa shi da manganese dioxide wanda aka haɗa da sinadarai wanda ke inganta aikin batirin Leclanché. Daga baya, an yi amfani da manganese dioxide (EMD) wanda aka shirya ta hanyar lantarki wanda ke ƙara ƙarfin ƙwayoyin halitta da ƙarfin aiki.
*Amfani da yawa a masana'antu sun haɗa da amfani da MnO2 a cikin yumbu da yin gilashi a matsayin launin da ba shi da wani sinadari. Ana amfani da shi wajen yin gilashi don cire launin kore da ƙazanta na ƙarfe ke haifarwa. Don yin gilashin amethyst, canza launi, da fenti a kan faranti, faience, da majolica;
*Ana amfani da ruwan MnO2 a fannin fasahar lantarki, fenti, ganga masu launin ruwan kasa, a matsayin busarwa don fenti da varnish, da kuma don bugawa da rini a yadi;
Ana amfani da *MnO2 a matsayin pigment kuma a matsayin abin da zai maye gurbin sauran mahadi na manganese, kamar KMnO4. Ana amfani da shi a matsayin reagent a cikin hadadden halitta, misali, don oxidation na allylic alcohols.
