Every ceramic company provides its own “body” composition articulated by raw materials and various clays. Due to low cost and tradition, some companies use sodium silicate and sodium carbonate as deflocculates. The uses of alkaline substances are likely to induce change crystallography or in the chemical composition of the clays used in the ‘body’.

On the other hand, STPP/SHMP suffer reversion or degradation to orthophosphates through hydrolysis during the process of grinding in ball mills. Orthophosphates are not active dispersants as they are anions that may actually favor flocculation or settling.

Innovative processes for ceramics manufacturing involve the use of organic auxiliaries in order to provide the ceramic body with the right flow behavior and cohesion properties. When the preparation of ceramic bodies is done via the slip phase, the use of hydro soluble polymers is required most of the time.
