thixotropy

 [thik-sot´rah-pe]
the property of certain gels of becoming fluid when shaken or otherwise agitated and then becoming semisolid again at rest.

thix·ot·ro·py

(thik-sot'rŏ-pē),
1. The property of certain gels of becoming less viscous when shaken or subjected to shearing forces and returning to the original viscosity on standing (for example, synovial fluid, ferrous hydroxide gel).
2. A characteristic of a system exhibiting a decrease in viscosity with an increase in the rate of shear, usually a function of time.

Among other qualities, fumed special silica grades made by Evonik optimize rheology, viscosity and thixotropy of liquid and gel-like formulations as well as suspension properties of pigments and fillers they contain.
The main functions that fumed silica performs include thickening liquid compositions, imparting thixotropy to them, and helping suspend any solid particles; a network is formed owing to the small size of the silica particles that results in a large surface area per unit volume and also due to the presence of SiOH groups on the surface (5).
