The motion of suspended solids in nonuniform electric fields in liquid dielectrics is called dielectrophoresis. Some of the quantitative aspects of dielectrophoretic behavior of solids is reported herein. The yield of precipitated solids is seen to rise with applied voltage in cells of cylindrical geometry, until a critical or “sluff‐off” voltage is reached. The yield is seen to decrease with increase of volume fraction of suspended solids in the range of 1 to 50% v/v. The yield depends on voltage gradient, applied potential, cell dimensions, and relative dielectric constants of solid and liquid. In particles of given size, yield is observed to be directly dependent on the dielectric constant. Moisture is shown to have a small but demonstrable effect. As expected, the amount and character of dielectrophoretic behavior is observed to be independent of the direction of the field applied.
