Abstract:The mechanism of solid state chemistry reaction and its influencing factors were introduced, and the concept of mechanically activated solid state chemical reaction was put forward. The effect of mechanical power on solid state chemical reaction was discussed. The active process of mechano-chemistry, active mechanism of mechanically activated solid state chemical reaction and solid-state diffusion were studied respectively. The mechanisms of mechanically activated solid state chemical reaction, such as refinement of particles, grain refining and defect increasing, localized heating-up, etc were suggested. They made the reaction has bigger reacton area, increased the diffusion coefficient, decreased activation energy of solid reaction.
