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.

A detailed look and what deflocculation is, what the most common types of deflocculants are (there are many) and how they compare in function
Glossary Deflocculation
Deflocculation is the magic behind the ceramic casting process, it enables slurries having impossibly low water contents and ware having amazingly low drying shrinkage
