| TANG Lin; et al.（Central South Forestry University; Hunan Changsha; 410004; China） |
| Abstract：Superfines Mn 3O 4 was prepared by the hydrothermal method, using ethanol and potassium permanganate as stocks. Based on orthogonal experiment. The influential factors such as temperature, time, concentration and the acid-basic character were investigated. The product was analyzed by X-ray powder diffraction patterns, Scan electron microscope. The result showed that the Mn 3O 4 is single-phase and the particle size is 50～90nm. |
| Key words：hydrothermal method; orthogonal experiment; additive |
