Preparation and microstructure of nanometer-sized Mn2O3

Abstract Nano-Mn 2 O 3 material has been prepared by a chemical method and its microstructure has been studied by X-ray Diffraction (XRD) and Transmission Electron Microscopy (TEM). The experimental evidence suggests that the different preparation conditions, such as the annealing temperature and time, the dripping speed of the NaOH solution, pH value during solution reaction and so on, have a great effect on the microstructure of nano-Mn 2 O 3 .
