Abstract
The electrical properties of systems of , were examined in detail. The conductivity and the sinterability increased with the amount of excess lithium oxide in the phosphate. The secondary phase acts as a flux to accelerate the sintering process and to obtain high conductivity grain boundaries. The conductivity decreased and the activation energy of the bulk component for Li + migration increased by the partial substitution of Tr 4+ for M 4+ in systems of . A minimum activation energy of 0.28–0.30 eV, was obtained for the sample with ca. 1310 Å 3 in the cell volume. has the most suitable tunnel size for a Li + migration through the NASICON‐type network structure.
