The importance of zeta potential in ceramic processing (2) Zirconia

Polymers are used in ceramic processing for a variety of purposes, and the effect on the ceramic slurry will depend on their adsorption behaviour. Zeta potential can be used to investigate the competitive absorption of mixtures of polymers. 

In order to obtain highly dense and homogeneous dispersions, polymeric reagents are utilized. Polyelectrolytes, in particular polyacrylic acid and its derivatives, have been widely used as effective dispersants, while binders and plasticizers like polyvinyl alcohol and glycols are commonly employed in the aqueous tape casting of ceramic powders...
