This investigation aims to answer the vexing question that has been with the colloidal science community for a long time, on whether we can use zeta potential data of dilute suspension to correlate with rheological parameters obtained at a much higher solid loading where the mismatch of surface properties is one of the main issue. In this study, sequential yield stress and zeta potential measurements...
The effects of salicylic (2-hydroxybenzoic), 3-hydroxybenzoic, 4-hydroxybenzoic, 3,4-dihydroxybenzoic and 2,3,4-trihydroxybenzoic acids adsorbed additives on the zeta potential-pH and yield stress-pH behaviours of α-Al 2 O 3 suspensions were investigated. With careful selection of the type and nature of adsorbed additives, molecular attribute and surface forces relationship has been...
The effects of adsorbed ethylenediaminetetracetic (EDTA), nitrilotriacetic (NTA) and (S,S)-ethylenediamine-N,N′-disuccinic (EDDS) acids on the yield stress of α-Al 2 O 3 suspensions were evaluated to determine the nature of the inter- or intra-molecular forces responsible for the type of surface forces operating in the suspension. The conformational structures of the adsorbed additives...
