Abstract

  The colloidal particles dispersed in liquid self-assemble into “crystal” structure, where the particles arrange regularly, under appropriate condition. The crystallization of colloids has been studied as a model to study phase transition in atomic/molecular systems. We can observe both melt growth like process and solution growth like process in colloidal systems depending on the interaction between colloidal particles. For attractive interaction, the crystallization is solution growth like. The particle densities in liquid and crystal phases are significantly different from each other. Here, I describe solution growth of colloidal systems and exclusion of impurity particle on the growth process from the viewpoint of the difference of the interparticle interaction between main component and impurity particles. The attractive interaction is caused by depletion attraction by depletant molecules, which are added into the colloidal dispersion as the secondary component. I also report some examples of impurity exclusion.
