Three manganese compounds, Mn3O4, β-MnO(OH) and δ-MnO2 were prepared by oxidizing amnioniacal alkaline solution of manganese(ll) sulfate with gaseous oxygen at 10°C.Their formation were identified by X-ray powder diffraction method.The fine structure of these manganese compounds were obser ved by transmission electron microscops. Three kinds of lattice planes, [211], [220], and [112] were found in Mn3O4. Whereas only [001] planes were observable in β-MnO(OH) and δ-MnO2. Especially in δ-MnO2, dislocation was recognized.
