Abstract: Through mechanical urged the solid material crystal structure and physical and chemical properties change method called mechanical activation. In order to study the mechanical activation of zinc oxide and iron oxide reduction temperature, the influence of the carbon thermal reduction reaction thermodynamics calculation and analysis. Based on comparison of reaction Gibbs free energy parameters calculation, the results show that the mechanical energy storage of carbon will not only make the beginning of ferric oxide and zinc oxide reduction temperature decreased significantly, and improve the ability of powdered carbon reduction, has reached the requirement of saving energy and reducing consumption. The beginning of the zinc oxide reduction temperature reduced about 185 ℃, the beginning of the hematite reduction temperature decreased around 105 ℃.Temperature decrease from the perspective of thermodynamics analysis is the main reasons for carbon produced in the process of mechanical activation lattice distortion energy and surface energy, which can to lattice distortion caused by the dislocation and no standard for the major source of energy storage.
