Details

Zeta potential is one of the most important parameter in colloidal processing of ceramic powder. Zeta potential indicates the degree of repulsion between adjacent, similarly charged powder particles in a suspension. A high zeta potential will confer stability, i.e. the solution or dispersion will resist aggregation. The center has one zeta potential analyzer, based on electrokinetic phenomena of the charged particles when an electric field is applied across the dispersion.
