It is important to optimize the slurry composition in order to obtain high green density low green shrinkage and sufficient green strength to produce defect free demolding.
Ceramic slurry dispersant.
Therefore dispersant should be added to make the ceramic particles disperse uniformly within the slurry.
To produce ceramics with the best properties and to facilitate ball milling or spray drying a dispersant is normally added to the ceramic slurry.
At a high level dispersants are used in ceramic formulations to wet and disperse fine powders in media like water and for rheology control.

Dispersants can help to decrease viscosity and help achieve a narrow particle size distribution by reducing agglomeration.
