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.
To produce ceramics with the best properties and to facilitate ball milling or spray drying a dispersant is normally added to the ceramic slurry.
Therefore dispersant should be added to make the ceramic particles disperse uniformly within the slurry.

Dispersants can help to decrease viscosity and help achieve a narrow particle size distribution by reducing agglomeration.
In this section five different kinds of dispersant kos110 17000 20000 27000 and a kos110 17000 dual dispersant with a mass ratio of 1 1 were used.
