Sc-substituted $La_{0.6}Sr_{0.4}FeO_{3-{\delta}}$(LSFSc) has synthesized for ceramic interconnector of tubular solid oxide cells (SOCs). For improving the redox stability and electric conductivity of LSFSc, the compositions of Sc, pH value of mixed precursors, calcination temperature and times were optimizing. The electrochemical performances of $La_{0.6}Sr_{0.4}Fe_{1-x}Sc_xO_{3-{\delta}}$ powders were measured as depending on Sc composition. The electric conductivity and redox stability of $La_{0.6}Sr_{0.4}Fe_{1-x}Sc_xO_{3-{\delta}}$ was determined by Sc concentration. $La_{0.6}Sr_{0.4}Fe_{0.9}Sc_{0.1}O_{3-{\delta}}$ powders can be one of the stable composition for ceramic interconnector of tubular-SOCs.
