![]() ![]() Furthermore, this ultrafast sample synthesis can significantly save material synthesis time and thus has the obvious advantage for large-scale production. The zTs of 0.8 at 390 K and 0.6 at 450 K are obtained for Ag 2Se and CuAgSe, respectively, which is comparable with the values in the materials prepared by the traditional method. Silver is located in Group 11 (Ib) and Period 5 of the periodic table, between copper (Period 4) and gold (Period 6), and its physical and chemical properties are intermediate between those two metals. The influence of SPS heating rate on the phase composition, microstructure, and thermoelectric properties, including Seebeck coefficient, electrical conductivity, and thermal conductivity, were investigated. silver (Ag), chemical element, a white lustrous metal valued for its decorative beauty and electrical conductivity. ![]() In this work, phase-pure polycrystalline Ag 2Se and CuAgSe compounds were synthesized from raw elemental powders directly by manual mixing followed by spark plasma sintering (MM-SPS) in a few minutes. ![]() The traditional melting–annealing–sintering processes are used to grow Ag 2Se and CuAgSe materials with the disadvantages of high costs of energy and time.
