TLDR
A theory of the opacity of bentonite water suspensions as a function of the shear rate is given in this paper, where the experimental opacity behavior confirms previous theoretical predictions of the aggregate size distribution.Abstract:
A theory of the opacity of bentonite‐water suspensions as a function of the shear rate is given. The experimental opacity behavior confirms previous theoretical predictions of the aggregate size distribution. The extinction coefficient of bentonite was determined at two wavelengths.read more

Thixotropy - a general review
TL;DR: In this paper, the evolution of the concept is traced back and a generalized definition is accepted, and various experimental methods are considered with which meaningful measurements of thixotropy can be performed.

Flow properties of coagulated colloidal suspensions
Bruce Firth,Robert J. Hunter +1 more
TL;DR: In this article, the flow properties of electrically charged, but unstable, colloidal sols are investigated in the light of three possible models, i.e., hard (nondeformable) floc, elastic floc and hard (non-nondefinite) particle model, and they are shown to provide a consistent physical interpretation of both the linear region of the flow curve and the Bingham yield value.
Journal ArticleDOI
Flow properties of coagulated colloidal suspensions: II. Experimental properties of the flow curve parameters
TL;DR: In this paper, the relationship between the experimental flow parameters and the colloidal parameters (volume fraction, particle size, and interactive forces) is examined and ten such relationships can be used to test the validity of possible models of the flow of coagulated suspensions.

The energy dissipation in sheared coagulated sols
T.G.M van de Ven,R. J. Hunter +1 more
TL;DR: In this paper, the authors assume that the basic units of flow are elastic flocs which are slightly deformed during collisions because of the stretching of the particle bonds within a floc by a few tenths of a nanometer.

Intrinsic viscosities and other rheological properties of flocculated suspensions of nonmagnetic and magnetic ferric oxides
Thor L. Smith,Calvin A. Bruce +1 more
TL;DR: In this article, the viscosity of flocculated suspensions of rhombohedral and acicular (needle-like) particles in ethylene glycol was measured over broad ranges of concentration at shear rates D from a few sec−1 up to 1340sec−1.
