摘要
Rheological properties of concentrated alumina suspensions using a charged copolymer as the dispersant have been studied. The non-Newtonian behavior of these fluids was characterized and correlated to zeta potential measurements and sedimentation column data, obtained with these dispersions. As a result, a clear relationship between dispersion stability and pseudoplastic/dilatant rheological behavior was established.
