The Sc 3+ ion migration in the scandium tungstate solid was qualitatively demonstrated. For clarifying the exact migrant quantitatively, modified Tubandt electrolysis was performed for the Sc 2 (WO 4 ) 3 solid. As a result of the strict compensation, that is, vaporization and adherence compensations, a weight increase at the cathodic side and a weight decrease at the anodic side were reproducibly observed after the electrolysis. In addition, the Sc concentration at the cathodic side was increased and a corresponding decrease at the anodic side was observed. Therefore, the Sc 3+ ion conduction in the Sc 2 (WO 4 ) 3 solid was quantitatively demonstrated.
