✦ Synopsis

Electrokinetic characteristics of insoluble particles in dispersion were shown to be dependent upon the existing charge on the particle surface as related to the polarity of the dispersing solvent. A procedure is described for observing the electrophoretic mobility of charged particles from which the zeta potential can be calculated. The magnitude of the zeta potential was used as an index of caking. The electrical discharge of particles by flocculating techniques led to a reduction in the caking tendency of the dispersed particles.
