..., spheroidal solids floating in the liquid. Stirring at high speeds creates a high shear rate, which tends to reduce the viscosity of the slurry even at solid fractions as high as 50 to 60% volume. The process of casting such a slurry is called rheocasting . The slurry can also be mixed with particulates...
