Preparation of concentrated aqueous alumina suspensions ...
Jan 01, 1997· To prevent competitive adsorption of the binder with the dispersant, which leads to an increase in the viscosity and in the elastic modulus of the suspension, the binder was mixed very slowly for a short time in a ball mill. In the presence of the binder the optimum amount of dispersant was mg m −2 (dry weight basis). These suspensions ...
