Quid est Manganese Dioxide usus est?
*Manganese Dioxide naturaliter accidit sicut pyrolusite mineralis, qui est fons manganese et omnium eius compositorum;Solebant facere ferrum manganesum sicut oxidizer.
*MnO2 principaliter ponitur ut gravida pars cellae aridae: gravida alcalina et cellula Leclanché sic dicta, seu gravida zinci-carbon.Manganese Dioxide feliciter usus est ut materia machinalis et copiosa.Initio, naturaliter MnO2 occurrens adhibitum, sequitur chemicum manganesum dioxydum manganesum in melius substantialiter emendandum Leclanché batteries perficiendum.Postea, efficacius electrochemice parato dioxide manganese (EMD) applicata est facultatem cellulam ac rate facultatem augendi.
Multi usus industriae in ceramicis et vitreis faciendis sicut pigmento inorganico utuntur MnO2 includuntur.Adhibetur in vitreis ad tollendum fucum viridem ex ferro immunditiae causatum.Ad faciendum amethystum vitrum, vitrum colorantem, et pingendum super murrina, fausta, et majolica;
*MnO2 praecipitatio adhibetur in electrotechnicis, pigmentis, stativis doliis sclopetis, ut siccioribus pro fucis et varnishibus, ac pro imprimendis et tingendis textilibus;
*MnO2 adhibetur ut pigmentum et praecursorem aliis compositis manganesis, ut KMnO4.Ponitur pro reagens in synthesi organica, verbi gratia, pro oxidatione alcoholorum alllicorum.
*MnO2 medicamentis quoque in aqua curatio adhibetur.
