An analytical procedure is developed which provides the magnitudes of the space charge potential and the corresponding grain boundary energy in ionic oxides from the effect of an applied dc electric field on grain growth. Reasonable agreement occurred between the calculated values and expectations or other measurements. The agreement indicates that the physical mechanism governing the retardation of grain growth by an electric field in 3Y‐TZP is through reduction in the grain boundary energy by the interaction of the field with the space charge.
