✦ Synopsis

The lithium ionic conductivity of materials prepared by reaction of lithium iodide with anhydrous and hydrated aluminum sulfate has been investigated by a.c. conductivity and n.m.r, techniques. The a.c. measurements indicated thermally activated diffusion with an activation energy of 8.3 kcal/ tool. From 7Li n.m.r., the characteristic time of motion, re, was determined from the observed line width at a given temperature. The plot of log re as a function of 1/T is linear and gives an activation energy of 6.3 kcal/mol.
