Interfacial conduction in lithium iodide containing inert oxides

Temperature-dependent conductivities are reported for a lithium iodide sample sandwiched between two fused silica plates and for an LiI film deposited on a silica plate. The existence of an LiISiO2 interfacial conduction path possessing a conductivity of about 5 ohm−1 cm−1 at 25 °C is confirmed. In addition, an infiltration technique for the preparation of LiI-ceramic particle composites is discussed.
