Which dispersant do you think might be more appropriate to use as a starting point to prepare a water based slurry composed of ceramic of micron sized particles.
Ceramic slurry dispersant.
Ammonium citrate and polyethylenimine have been.
To produce ceramics with the best properties and to facilitate ball milling or spray drying a dispersant is normally added to the ceramic slurry.
Dispersants can help to decrease viscosity and help achieve a narrow particle size distribution by reducing agglomeration.
Ceramic slurry is obtained by mixing ceramic powder carrying vehicle binder and dispersant to produce uniformly dispersed ceramic slurry.
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.
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.
