Chii chinonzi Manganese Dioxide chinoshandiswa?
*Manganese Dioxide inowanzoitika semaminerari pyrolusite, inova kunobva manganese nezvose zvayo zvinosanganiswa; Inoshandiswa kugadzira manganese simbi seoxidizer.
*MnO2 inonyanya kushandiswa sechikamu chemabhatiri emasero akaoma: mabhatiri ealkaline uye anonzi Leclanché cell, kana zinc-carbon mabhatiri. Manganese Dioxide yakashandiswa zvakabudirira seyakachipa uye yakawanda bhatiri zvinhu. Pakutanga, MnO2 inongoitika yaishandiswa ichiteverwa nemakemikari akagadzirwa manganese dioxide zvakanyanya kunatsiridza mashandiro emabhatiri eLeclanché. Gare gare, iyo yakanyanya kunyatsoshanda electrochemically yakagadzirira manganese dioxide (EMD) yakashandiswa inosimudzira masero kugona uye chiyero kugona.
*Kushandiswa kwakawanda kwemaindasitiri kunosanganisira kushandiswa kweMnO2 mumakeramiki uye kugadzira magirazi senge inorganic pigment. Inoshandiswa mukugadzira magirazi kubvisa green tint inokonzerwa nesimbi tsvina. Pakugadzira girazi reametiste, girazi rinobvisa ruvara, uye kupenda pane porcelain, faience, uye majolica;
*Kunaya kweMnO2 kunoshandiswa muma electrotechnics, pigments, browning gun barrels, as drier for paints and varnishes, and kudhinda nekudhaya machira;
* MnO2 inoshandiswawo se pigment uye sefanotangira kune mamwe manganese makomisheni, akadai seKMnO4. Iyo inoshandiswa se reagent mune organic synthesis, semuenzaniso, kune oxidation yeallic alcohols.
* MnO2 inoshandiswawo mumashandisirwo ekurapa mvura.
