Abstract
Inventia se refera la un procedeu de obtinere a oxidului mangano-manganic, care folosind ca materie prima carbonatul de mangan, acesta este supus solubilizarii cu acid azotic, la pH = 0,5...1,0 urmata de precipitarea hidroxidului de mangan cu solutii de hidroxid de amoniu 20%, la pH = 7,5...8,0 si de calcinarea hidroxidului de mangan la 600...650 degree C.
