Kedu ihe a na-eji manganese dioxide eme ihe?
* Manganese Dioxide na-apụtakarị dị ka pyrolusite ịnweta, nke bụ isi iyi nke manganese na ogige ya niile; A na-eji ya eme ígwè manganese dị ka oxidizer.
* MnO2 bụ nke a na-eji dịka akụkụ nke batrị cell kpọrọ nkụ: batrị alkaline na ihe a na-akpọ Leclanché cell, ma ọ bụ batrị zinc-carbon. Ejila manganese dioxide mee ihe nke ọma dị ka ihe batrị dị ọnụ ala yana bara ụba. Na mbụ, a na-eji MnO2 na-eme n'ọdịdị ya wee soro manganese dioxide na-emepụta kemịkal na-eme ka arụmọrụ nke batrị Leclanché dịkwuo mma. Mgbe e mesịrị, a na-etinye manganese dioxide (EMD) nke a kwadebere nke ọma nke ọma na-eme ka ikike cell na ike ọnụego dịkwuo elu.
