Simulation for Ordering of Suspended Particles.

The ordering of colloidal particles in various electrolyte concentrations is simulated using the Monte Carlo method, in which interaction between particles is described by the DLVO theory. Two types of ordering mechanism are found : one is due to attraction of interparticle potential, the other to repulsion of interparticle potential. Since the attractive particles arrange themselves after clustering, they form an ordered structure more slowly than do repulsive particles.
