Abstract
An investigation of the effects of axial direct current during a zone refining process has been continued. Optimum current direction and limiting current densities have been established. Results for germanium indicate that the segregation rate is increased when the current flows opposite to the direction of zone travel, and is decreased when the current is reversed. The magnitude of the effect is larger than the theoretical rate of diffusion of ions in an electric field, and the optimum current direction is opposite to that predicted from considerations of interface stability due to the Peltier effect.
