Gịnị ka a na-eji Manganese Dioxide eme?
*Manganese Dioxide na-apụta n'onwe ya dị ka pyrolusite mineral, nke bụ isi iyi nke manganese na ihe niile dị na ya; A na-eji ya eme ígwè manganese dị ka ihe na-eme ka ọ dị ọcha.
*A na-ejikarị MnO2 eme ihe dị ka akụkụ nke batrị sel akọrọ: batrị alkaline na ihe a na-akpọ sel Leclanché, ma ọ bụ batrị zinc-carbon. A na-eji Manganese Dioxide eme ihe nke ọma dị ka ihe batrị dị ọnụ ala ma baa ụba. Na mbụ, e jiri MnO2 nke sitere n'okike mee ihe, wee jiri manganese dioxide emepụta kemịkalụ nke na-eme ka arụmọrụ nke batrị Leclanché ka mma.
