Abstract

Ag_4.64Pb₂O_5.87, a silver and oxygen defects phase of Ag₅Pb₂O₆, was prepared by solid state reaction of Ag₂O and PbO at 773 K in O₂ of 1.2 MPa. The crystal structure was analyzed by the Rietveld method using X-ray powder diffraction data. The c-axis length changed from 6.427 to 6.433 Å in 0.25<x<0.50 while the a-axis length was almost constant around 5.942 Å. Ag_4.64Pb₂O_5.87 exhibited metallic temperature dependence of electrical resistivity in the temperature range of 10-400 K. The value of the resistivity was in the order of 10^-4 Ωcm. The Seebeck coefficient ranged from -4 to 0 μV/K below 300 K, which revealed that the main conductive carrier is electron. Diamagnetism of the order of 10^-7 emu/g was measured at 5-350 K.
