Manganese Dioxide e sebelisetsoa eng?
*Manganese Dioxide e hlaha ka tlhaho e le pyrolusite ea diminerale, e leng mohloli oa manganese le metsoako eohle ea eona; E sebelisoa ho etsa tšepe ea manganese e le oxidizer.
*MnO2 e sebediswa haholoholo e le karolo ya dibetri tsa sele e ommeng: dibetri tsa alkaline le seo ho thweng ke sele ya Leclanché, kapa dibetri tsa zinki-khabone. Manganese Dioxide e sebedisitswe ka katleho e le thepa ya betri e theko e tlase le e ngata. Qalong, MnO2 e hlahang ka tlhaho e ile ya sebediswa mme ya latelwa ke manganese dioxide e entsweng ka dikhemikhale e ntlafatsang tshebetso ya dibetri tsa Leclanché haholo. Hamorao, manganese dioxide (EMD) e lokisitsweng ka electrochemical e ile ya sebediswa e ntlafatsang bokgoni ba disele le bokgoni ba ho lekanya.
