Abstract
The stability of suspensions of calcium pyrophosphate was investigated using the techniques of electrophoresis and electroacoustics to measure the zeta potential of the suspensions. The effect of pH changes, adsorption of SDS and Triton-X and the addition of KCl were investigated using electrophoresis. The stability of the suspensions were also calculated from the theoretical kappa delta(theta) values. Finally, the effect of plasma treatment of the powder was investigated using the relatively new technique of electroacoustics to study more concentrated aqueous suspensions of the powders. From the resulting data it was possible to identify the optimum processing conditions of these powders.
