The reaction between metallic Ag and PbS1.18(TiS2)(n), n=l, 2, misfit layer
compounds has been investigated by electrochemical technique, X-ray powder
analysis and transmission electron microscopy. It was found that silver in
tercalation is possible only in the compound with n = 2. The thermodynamic
behavior and location of phase boundaries were studied in the temperature r
ange 400-650 K. DC-conductivity and magnetic-susceptibility measurements we
re performed, and the data can be interpreted as an appearance of small pol
arons during silver insertion. (C) 2001 Elsevier Science B.V. All rights re
