The adhesion of a powder is brought about, in addition to friction, also by an adhesive force H which is inversely proportional to grain diameter. The proportionality factor h is a material constant characteristic of a given powderfoundation system, and has the dimension of surface tension. When h is known, the average grain diameter of powders of unknown grain size may be determined by adhesion measurements.
