Abstract

This paper aims to summarize the series of investigations on coupling suspension yield stress and DLVO (Derjaguin-Landau-Verwey-Overbeek) forces, i.e. van der Waals and electrical double layer forces. This summary provides a better understanding of the basic phenomena associated, historical development and current status of this useful coupling, and also discusses the applicability and limitations/variations of such coupling applied to different types of concentrated aqueous particle suspensions. Aqueous suspensions discussed are composed of charged inorganic fine particles, including metal oxide colloidal particles, mineral fine particles, and clays. The research gaps are identified and specific future perspectives are discussed to further enhance the use of this unique and useful coupling, and to aim for the transition from the modelling of similar particle suspension systems to its dissimilar/mix particle suspension systems that fit more with the current and future industry needs in particle processing.
