Abstract
Melting temperature (T m) of colloidal crystals of monodispersed polystyrene and silica spheres has been measured for thecompletely deionized suspensions as a function of sphere concentration. More than 3 weeks are needed before achievement of the completely deionized state.T mincreases substantially as the deionization process of the suspension proceeds. The most reliable values ofT mobserved for the completely deionized suspensions are successfully analyzed again with the theory of Williams et al. The newT mvalues are compared also with the theory of Robbins et al., which treats the repulsive Yukawa potential between colloidal spheres.
