| Abstract Scope |
Typically, the DLVO repulsive force is directly correlated to the zeta-potential; however, this correlation was observed to be flawed because the double-layer thickness and the subsequent charge decay (from the colloidal surface towards the bulk of the suspension) is not considered. Using elliptical integration techniques, the exact solution of the Poison-Boltzmann differential equation was able to be solved allowing for a more accurate representation of the repulsive force experienced between particles and the effect of the medium. Using the exact technique, 121 different particle-medium combinations were modeled. Potential candidate systems for dispersion have been identified by changing the medium in which the ceramic particles are dispersed without use of an additional surfactant additive for use in processing methods utilizing non-aqueous mediums. |
