对于单粒径球形颗粒的水胶体体系，计算了亚微米级带电颗粒间的相互作用能随颗粒间距离或固体含量的变化。计算结果揭示了表面势效应和颗粒尺寸效应对相互作用能的影响。根据带电粒子间的相互作用能，建立了单组分胶体体系的亚稳相图。该相图表明，较小颗粒的胶体悬浮液的性质在较低固体含量下接近胶体固体。
Interaction energy between charged particles in submicron size range was calculated as a function of distance between particles or solid content for an aqueous colloidal system of monosize spherical particles. This calculation revealed the surface potential effect and particle size effect on the interaction energy. A metastable phase diagram for one-component colloidal system was constructed on the basis of the interaction energy between two charged particles. This phase diagram suggests that nature of colloidal suspensions of smaller particles approaches colloidal solid at lower solid contents.
