WebbWhile a slurry can display obvious fluid properties, at very low stresses it has the potential to react as a solid. The zero-shear viscosity can aid with stability, preventing the solid particles from settling to the bottom of the solution. The yield stress of the slurry is the amount of force needed to elicit significant flow.
