摘要: With the aid of the critical size of colloidal cluster, the critical volume fraction of phase transition of colloidal system is determined by the principle of entropy maximum and Carnahan–Starling (CS) state equation in this paper. In our discussion, no parameter is introduced externally, and our results are in good agreement with the experimental results.
