Ag-added (Ca 0.975 La 0.025 ) 3 Co 4 O 9 ceramics were fabricated using spark plasma sintering from the precursor powder synthesized by a polyacrylamide gel method. The results indicated that Ag precipitated as a second phase in Ca 3 Co 4 O 9 matrix. The addition of Ag was effective in enhancing the
