where '/b is the viscosity of the binder, (P\s the solids loading, fPm is the maximum particle packing density, and n is a constant usually close to 2. A is a function that accounts for shear rate, temperature, and particle size effects. In principle, some or all of the above factors can be controlled to allow molding at low shear rate conditions. In LPM practice, however, the suspension viscosity is usually reduced by lowering Vb. Typical examples of LPM techniques are discussed next.
