摘要

In this study different characteristics regarding to dispersion of a suspension containing precursor particles with respect to charge, particle size and Theological measurements were investigated. Ammonium poly carboxylate (APC) was used here as a dispersing agent. From our investigations it was exhibited that point zero charge (PZC) for precursor particles is about 6.5-7. On the other hand, it was revealed that surface charge of precursor particles was changed significantly in presence of ammonium poly carboxylate agent, and also PZC amounts shifted toward lower acidic pHs in the range of 4.04-4.4.
