Abstract

When subjected to low stresses, an abrupt cessation of flow (solidification) is observed in concentrated dispersions of hard sphere-like colloidal particles. This is due to the formation of colloidal crystals, as evidenced by opalescence when illuminated by white light. The elastic polycrystalline structure is stable if unperturbed but can be destroyed by exceeding a yield stress.
