Abstract
Stable aqueous Al2O3 suspensions that can be flocculated by increasing temp erature were prepared using tri-ammonium citrate and poly(acrylic acid) (PA A). Effects of particle volume fraction on the rheological properties of Al 2O3 suspensions were investigated. The modified Dougherty-Krieger equations were used to describe the volume fraction dependence of relative viscosity for both the PAA-addition and PAA-free suspensions. An equation using perc olation model was proposed to analyze the temperature and volume fraction d ependence of the relative viscosity of the suspensions. The calculated resu lts were in good agreement with the experimental data.
