Maxaa Manganese Dioxide loo isticmaalaa?
* Manganese Dioxide waxay si dabiici ah u dhacdaa sida macdanta pyrolusite, taas oo ah isha manganese iyo dhammaan xeryihiisa; Waxaa loo isticmaalaa in lagu sameeyo birta manganese sida oksidizer.
*MnO2 waxaa inta badan loo isticmaalaa qayb ka mid ah baytariyada unugga qalalan: baytariyada alkaline iyo waxa loogu yeero unugga Leclanché, ama baytariyada zinc-kaarbon. Manganese Dioxide ayaa si guul leh loogu isticmaalay sidii walxo batari oo jaban oo badan. Markii hore, MnO2 si dabiici ah ayaa loo isticmaalay oo ay ku xigtay manganese dioxide kiimikaad lagu farsameeyay oo si weyn u wanaajisay waxqabadka baytariyada Leclanché. Ka dib, manganese dioxide (EMD) oo si hufan loo diyaariyey ayaa lagu dabaqay kor u qaadida awoodda unugyada iyo awoodda heerka.
Isticmaalo badan oo warshadeed waxaa ka mid ah isticmaalka MnO2 ee dhoobada iyo samaynta dhalooyinka sida midab aan organic ahayn. Loo isticmaalo samaynta dhalada si looga saaro midabka cagaaran ee ay keento wasakhowga birta. Samaynta muraayadda amethyst, dhalooyinka midabaynta, iyo rinjiyeynta maraqa, faience, iyo majolica;
* Da'da MnO2 waxaa loo isticmaalaa farsamada elektiroonigga ah, midabka midabada, fuustooyinka qoriga bunni, sida qalajiyaha rinjiga iyo varnisheska, iyo daabacaadda iyo midabaynta dunta;
*MnO2 waxa kale oo loo isticmaalaa midab ahaan iyo horudhac u ah xeryahooda kale ee manganese, sida KMnO4. Waxaa loo isticmaalaa sidii reagent ee isku-dhafka dabiiciga ah, tusaale ahaan, oksaydhka alkolada allylic.
*MnO2 ayaa sidoo kale loo isticmaalaa codsiyada daaweynta biyaha.
