| Abstract: | A method for preparing Mn 3O 4 of electronic grade from microcrystal electrolysis dioxide manganese (EMD) is reported. The effects of some technological conditions on the production process and the effects of roasting time and roasting temperature on the inversion ratio of Mn 3O 4 are presented. Then, the properties of Mn 3O 4 are characterized by XRD, SEM and AAS. The results show that the high quality Mn 3O 4 may be made from microcrystal EMD. |
