Abstract

Polycrystalline samples of the ternary compound Pb₂Bi₄Te₅ were prepared by a solvothermal process based on the reaction between BiCl₃, Pb(NO₃)₂, Te, and KBH₄ in N,N-dimethylformamide (DMF), and followed by a post heat-treatment of compacted pellets. The microstructures of samples were characterized using XRD and SEM. The thermoelectric properties were determined by measuring the electric conductivity and the Seebeck coefficient. These samples show a disordered layered structure, with a maximum Seebeck coefficient of 84 μV/K around 520 K.
