Abstract (EN): The aim of the present work is to compare the influence of ionic strength on rheological properties of TiO2/Al2O3 suspensions at different volume fractions, and solid particle composition (1:1, 2:1, 1:2). The relative ratio of titania to alumina particles is important in determining the dispersion of the binary suspension with salt addition. In the case of systems containing the same number fraction of dissimilar oxides, the colloidal stability is mainly governed by the aggregation, as can be seen from the higher values of the stress in the flow curves and the yield stress values compared with those obtained in 2:1 and 1:2 situations. An attempt to provide a clearer picture concerning the stability determined by delicate balance between the van der Waals, and electrostatic, as well as the possible mechanisms of this balance tuned by environmental conditions has also been made. © 2008 American Institute of Physics.
