Abstract: Hydrotalcite [CdxMg6-xAl2(OH)16]2+[S·2H2O]2-doped with Cu2+ ion wassynthesized hydrothermally and the influence of the Cu2+ and Cd2+ ionic content, sulphurationtime and calcination temperature on the conductivity was studied.The results show that theconductivity increases with the increases of Cu2+ and Cd2+ content and sulphuration time inthe given ranges, and decreases beyond the ranges.The activation energies calculated withequation σ=σ0exp (-Ea/RT) in the ranges of temperatures from 323 Kto 363 Kand from383 Kto 523 Kare 76.55 kJ/mol and 7.18 kJ/mol, respectively.It is a good protonicconductor in the latter temperature range.
