Thermoelectric Properties of Spark-Plasma-Sintered Na1+xCo2O4 Ceramics

Year: 2003
Type: article
Abstract: Na1 + xCo2O4 ceramics were prepared by spark plasma sintering (SPS) and their thermoelectric properties were investigated from room temperature to 700°C in air. The SPS process with cover pellets technique is effective in obtaining highly densified single phase Na1 + xCo2O4 ceramics, typically 98% of the theoretical X-ray density, with lower resistivity. The power factor and figure of merit of the SPS treated NaCo2O4 ceramics attain 8.4 × 10-4 W·m-1·K-2 and ZT = 0.3 at 700°C, respectively.
