The dehydration of clay particles as a function of time was also investigated, and our observations show that it takes almost 10 h for the clay particles in the melted wax to reach the pure 0 WL hydration final state. However, the zero-to-one WL transition for clay particles being embedded in crystallized paraffin is very slow.

Deflocculants: A Detailed Overview - Digitalfire

Tripolyphosphate. This is a sodium phosphate triple-polymerised so as to form a single molecule with a chain structure. Its deflocculant power is shown by an increase in negative charge on the surface of the clay particles, via adsorption of the phosphoric anion, and therefore by an increase of zeta potential which causes repulsion between the particles.

The strength of fired clay comes from two processes that occur during firing. These are sintering and vitrification. Sintering occurs when the surfaces of the clay particles next to one another bond together. The clay particles also move closer to one another, so the clay becomes denser. Once clay is sintered, it changes from clay to ceramic.
