摘要：
The study illustrates how rheology and electrokinetics can be utilized in the investigation and optimization of the properties of ceramic suspensions. Zeta potential studies show that the isoelectric point of TiN particulates is at pH = 4, and for the pH range used, PMAA-NH4 addition results in a more negative zeta potential value. The rheological behavior of titanium nitride in the presence of PMAA-NH4 is strongly dependent on pH and three rheological types have been defined. (C) 1999 Published by Elsevier Science Ltd.
