Abstract

When silica particles (diameter 500–2000 Å) are immersed in a binary fluid (water + 2–6 lutidine) the stability of the colloids is affected by capillary interactions. For particular values of the mixture composition and of the fluid temperature, a flocculation of the colloids can be observed. This process is reversible and is accompanied by a large increase of tan absorbed layer of either lutidine or water, according to the origin of silica. This phenomenon, which is expected to be universal, can be related to the wetting and adsorption properties of solids in contact with fluid mixtures.
