✦ Synopsis

Solid solutions in the trivalent cationic conducting system (Lu 1-x M x ) 2 (WO 4 ) 3 (M = Er, Ho, Sm) that crystallize in the Sc 2 (WO 4 ) 3 type structure were prepared and their conducting behaviors were characterized electrochemically. The partial replacement of the Lu 3+ cation site in (Lu 1-x M x ) 2 (WO 4 ) 3 by larger M 3+ cations caused a crystal lattice expansion. Due to the opened ion-migration pathways, the solid solutions generally exhibited an increased cationic conductivity relative to pure Lu 2 (WO 4 ) 3 . The ion conductivity
