Abstract Interaction of Cu_2S with Cu_2O was investigated in the range of 1150 to 1250℃. The reaction rate increases with the increasing of surface area of Cu_2O grains and depends unobviously on the temperature. At the suggestion of the controlling step of reaction rate being oxygen diffusion through the liquid layer along interaction boundary, two final kinetical equations would be made as follows: α=6.69×10~(-2) At for 0

Key words: Cu_2O Cu_2S interaction kinetics
