Silver antimonate (AgSbO3) and silver (Ag) composites (Ag/AgSbO3) were synthesized by spark plasma (SP) sintering with the aim of realizing a thermoelectric material. The SP-sintered sample had higher relative density than normal-sintered (NS) one prepared by a conventional solid-state reaction method, reflecting its increased electrical conductivity (σ), decreased Seebeck coefficient (S), and increased thermal conductivity (κ). The increased σ contributed to an increased dimensionless figure of merit (ZT), and ZT of the SP sample was higher than that of the NP. In addition, it was proved that the formation of Sb3+ in AgSbO3 and that of Ag and AgSbO3 composite (Ag/AgSbO3) played an important role in enhancing the ZT value when compared with the ZT of defective AgSbO3, which included more amount of Sb5+ but not Ag.
