Methods for Preparing Manganese Oxide
The preparation of -Mn2O3 You can further alter or reduce Mn2O3 by using manganese dioxide, or heat divalent manganese salt at 600 to 800°C. To maintain a constant mass, you can also heat pure MnO2 at 650°C. Manganese nitrate Hexahydrate can be used as a raw materials. It must first be heated at at least 190°C to form a solid. Next, crush the material and heat at at least 650°C. The preparation of -Mn2O3 To make -MnO(OH), 350mL were of a solution with 2.2g of manganese. By heating, the thickening suspension emitting oxygen in dark brown to black color is rapidly boiled. Once the mixture has been boiled for approximately 4 minutes, it is separated and washed with 1.5L boiling water. Then, dry it with phosphorus pentoxide. To produce Mn2O3, the MnO (OH) was dehydrated carefully at 250°C and under low pressure for 3 days. Additionally, you can heat –MnO2 at 500°C under reduced pressure for up to 78 hours in order to make –Mn2O3.
