The growth of precipitates in a solution system is studied using the asymptotic method, taking into account the cross diffusion between solutes. The resulting asymptotic solution for the dynamic model of the precipitate growing in the solution reveals that the concentration distribution is significantly changed by the cross diffusion between solutes and the growth of precipitate depends not only on the self diffusion of solutes, but also on the diffusive interaction between solutes. The attractive diffusive interaction between solutes in the solution enhances the solute diffusion and facilitates the growth of precipitate, whereas the repulsive diffusive interaction between solutes depresses the solute diffusion and inhibits the growth of precipitate.
