ABSTRACT
When dispersed particles or solute ions have high charge densities, macroscopically homogeneous systems become microscopically inhomogeneous. Examples are the two-state structure of ordered structures in disordered region without boundary and the void structures. When the charge density is increased, the reentrant phase (liquid-solid-liquid) transition is found, which is not explainable in terms of the repulsion-only assumption. Furthermore, for relatively small charge particles and at an early stage of crystallization, spacefilling ordered states are first formed, disordered regions are then created inside the ordered domains, and crystal contraction thereafter takes place, causing the two-state structure. These may be explained by invoking a counterion-mediated attractive interaction between like-charged entities in addition to the widely accepted repulsion-only assmnption.
