    • The growth kinetics behaviors of CuO particles in reactive synthesis AgCuO composites were investigated by analyzing the reaction of copper and oxygen on the surface of a silver-copper alloy and calculating the precipitation amount of copper in the silvercopper alloy, the diffusion rate of copper in silver matrix and the size of CuO particles. It is indicated that the growth kinetics of CuO particles in the reactive synthesis process follows a parabolic law, the reaction of copper and oxygen on the surface of the silver-copper alloy is controlled by copper diffusion, and the growth of CuO particles is influenced by the content, diffusion rate and location (grains or grain boundaries) of copper in the silver-copper alloy. The calculated size of copper oxide particles agrees with the measured one.
