Non-additive Stabilization of Aqueous Alumina Suspensions by Binary Peg-Ester Dispersants: Composition Dependence, Phase Partitioning and Ph Response
Background: Stable aqueous alumina suspensions depend strongly on the molecular architecture and relative proportion of adsorbing dispersants.Methods: Two polyethylene-glycol (PEG) esterification-product families were investigated: an acrylic-acid/PEG product (X) and a citric-acid/PEG product (Y).Results: Orthogonal sc...
