Abstract
Sodium beta-alumina (β-NaAl11017) crystals were grown within a gel containing Na2O and Al2O3. The glass-crystal composite was put through a Na+ ↔ Ag+ ion-exchange reaction. The ion-exchanged glass-crystal was then subjected to an electrodeposition process. Nanosheets of metallic silver were found to have grown within the β-NaAl11017 channels which usually contain the mobile sodium ions. The DC electrical resistance of the composites was caused due to charge transport in the two-dimensional crystal planes. The average silver layer thickness was ~0.6 nm and the interlayer separation ~1.13 nm.
