【Abstract】 The oxidation kinetics of nickel pyrrhotite with air under microwave irradiation has been studied. In the course of oxidation, a nonlinear temperature rising state is caused by the phase tansformation, the microwave absorbility of the samples and the chemical reaction heat. The initial period and the later period of the reaction are under chemical control and diffusion respectively.更多还原
