000168208 5203_ $$aCa3Co4O9+x wt.% Ag (x=0, 1, 3, 5, and 10) polycrystalline thermoelectric ceramics have been prepared by a sol-gel route via nitrates followed by high temperature treatment before sintering. Out-of-plane XRD data have shown that major phase is the Ca3Co4O9 one, accompanied by metallic Ag. SEM observations have agreed with the XRD data. Apparent density measurements have revealed that all samples possess densities ranging between 80% and 90% when Ag content is raised. Mechanical properties have shown a drastic increase of bending stress when Ag is added to the samples. Electrical resistivity decreases with the Ag content, compared with the pure ones, while Seebeck coefficient slightly decreases. Maximum power factor values around 0.43mW/K2m at 800°C have been achieved for the 10wt.% Ag samples which is much higher than the measured in the pure Ca3Co4O9 samples.
