The effect of hydroxylated benzoic acid monomers on the colloidal stability of yttria–alumina binary aqueous suspensions is examined. The above property is also compared with those of citric acid, and polymethacrylic acid. It is observed that among the acids examined, only 2, 3‐dihydroxybenzoic acid effectively prevents a change in the viscosity of yttria–alumina binary aqueous suspensions versus time. This phenomenon is attributed to the lower tendency of 2, 3‐dihydroxybenzoic acid to adsorb dissolving yttrium ions from solution.
