Isetyenziselwa ntoni iManganese Dioxide?
*I-Manganese Dioxide ivela ngokwendalo njenge-mineral pyrolusite, engumthombo we-manganese kunye nazo zonke izinto zayo; Isetyenziselwa ukwenza intsimbi ye-manganese njenge-oxidizer.
*I-MnO2 isetyenziswa kakhulu njengenxalenye yeebhetri zeseli ezomileyo: iibhetri ze-alkaline kunye ne-Leclanché cell, okanye iibhetri ze-zinc-carbon. I-Manganese Dioxide isetyenziswe ngempumelelo njengezinto zebhetri ezingabizi kakhulu nezininzi. Ekuqaleni, i-MnO2 eyenzeka ngokwemvelo yasetyenziswa yaza yalandelwa yi-manganese dioxide eyenziwe ngeekhemikhali eyaphucula kakhulu ukusebenza kweebhetri zeLeclanché. Kamva, i-manganese dioxide (EMD) esebenza kakuhle ngombane yasetyenziswa ukuphucula amandla eseli kunye nokukwazi kwayo ukulinganisa.
*Iindlela ezininzi ezisetyenziswa kwimizi-mveliso ziquka ukusetyenziswa kwe-MnO2 kwi-ceramics nakwi-glass-making njenge-inorganic pigment. Isetyenziswa ekwenzeni iglasi ukususa umbala oluhlaza obangelwa kukungcola kwesinyithi. Ukwenza iglasi ye-amethyst, ukususa umbala kwiglasi, kunye nokupenda kwi-porcelain, i-faience, kunye ne-majolica;
*Ukukhanya kwe-MnO2 kusetyenziswa kwi-electrotechnics, kwi-pigment, kwi-browning gun barrels, njengomisa ngakumbi kwiipeyinti nakwii-varnishes, nasekuprinteni nasekudayeni amalaphu;
*I-MnO2 ikwasetyenziswa njenge-pigment kwaye njengesandulela sezinye iikhompawundi ze-manganese, ezifana ne-KMnO4. Isetyenziswa njenge-reagent kwi-organic synthesis, umzekelo, kwi-oxidation ye-allylic alcohols.
*I-MnO2 ikwasetyenziswa nakwiinkqubo zokunyanga amanzi.
