Slurry viscosity testing

WebbViscosity Testing of non-Newtonian Liquids Most samples we receive include soft multi-phase materials, typically including suspensions, gels or emulsions, which tend to be non-Newtonian fluids. Non-Newtonian fluids change their viscosity dependent upon the degree of shear applied. WebbViscosity is one tool used to measure and control rheology. Viscosity is a measure of the internal friction of a slurry. It measures and predicts how the slurry will flow and to some extent, how much will remain on the wax assembly. The slurry remaining on the assembly after drain is the foundation for the ceramic mold or shell.
