Zeta Potential

A phenomenon, which when understood, assists technicians to create better deflocculated ceramic slurries. It relates to the understanding the electrolytic interactions of minute particles in a suspension (colloidal science). It is the potential difference between the dispersion medium and the stationary layer of fluid attached to the dispersed particles.

Glossary	Deflocculation The deflocculation process is the magic behind the ceramic casting process. It enables you to make a slurry of far lower water content and thus lower shrinkage.
