| Abstract: | In this study, triamanganese tetraoxide was prepared by means of oxidizing Mn^2＋ with air in weak alkaline media under heating in water bath of 90 ℃. The effects of the starting concentration of MnCl2, the molar ratio of MnCl2 and hexamine and the polarity of the solution on the crystal form and morphology of the products were investigated. The as -prepared samples were characterized by X -ray diffraction and scanning electron microscopy. The results show that the products obtained under different conditions are all triamanganese tetraoxide which consists of well - crystallized spherical particles with high purity. |
