NUMERICAL METHOD TO DISCUSS THE MECHANISM OF NANO-MN FERRITE POWDER PREPARATION BY DETONATION OF EMULSION EXPLOSIVES
In the present research, the phase distribution of the detonation products of emulsion explosives used to prepare nano-MnFe 2O 4 powders by detonation is simulated by a numerical method. The mechanism of nano-MnFe 2O 4 powder synthesis via detonation of emulsion explosives is discussed and explained. The results obtained indicate that FeO and MnO form in the reaction zone before the Chapman–Jouguet detonation state is reached; these oxides react with surplus oxygen in air during the decrease in temperature and pressure, resulting in MnFe 2O 4 generation.
