On the other hand, powder contamination can be an issue with ball milling; ther fore, a protective atmosphere and ceramic milling jars and balls are recommended whe milling hard ceramic particles.
After ball milling, however, ceramic particles in a slurry have a tendency to reflocculate due to the unstable surface conditions induced through shear and impact forces of ball milling medium [[11], [12], [13]]. It has been well known that the addition of appropriate dispersants alters the surface properties so that the particles can remain ...
