Lithium ion conduction in -eucryptite (LiAlSiO4) and -eucryptite-AlPO4 solid solutions has been investigated by an ac impedance method between 423K and 673K over a frequency domain of 10 Hz - 500 kHz. Adding AlPO4 increases conductivity and lowers the activation energy. This finding suggests that phosphate addition creates some sites in which the lithium ions are less tightly bound to the lattice oxide ions than in the parent -eucryptite structure; it is these ions that account for the enhanced conductivity. The solid solutions have a composition of Li1-x AlSi1-xPxO4, where 0 x 0.4. 1982.
