 Abstract: The silver ionic conductivity in heterogeneous systems of AgBr:Al2O3
and AgI:Al2O3 is highly enhanced by utilizing mesoporous Al2O3 as the
insulating phase. The highest Ag+ conductivity of 3.1 X 10(-3)
Omega(-1) cm(-1) (at 25 degrees C) has been obtained for the AgI:Al2O3
composite with an Al2O3 volume fraction of 0.3. For AgBr:Al2O3, the
enhancement of the conductivity is satisfactorily explained in the
framework of the ideal space-charge model, while in the case of
AgI:Al2O3 stacking disorder is also considered to contribute to the
ionic conductivity.
