Rheological properties of concentrated aqueous silica suspensions: Effects of pH and ions content

Abstract

The relationship between the rheology concentrated aqueous silica suspensions and the particle interactions was investigated. The rheological characterization of these complex fluids requires an investigation of errors in the experimental measurements due to disturbances such as end effects and wall depletion effects. This paper presents a preliminary study of such effects for various rheometers equipped with Couette and vane geometries.
