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.

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. At a high level dispersants are used in ceramic formulations to wet and disperse fine powders in media like water and for rheology control. 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 is obtained by mixing ceramic powder carrying vehicle binder and dispersant to produce uniformly dispersed ceramic slurry. Therefore dispersant should be added to make the ceramic particles disperse uniformly within the slurry.
