In order to obtain information about the electrical properties of Pb8Na2- xLix(VO4)6 (0 ï‚£ x ï‚£ 2) apatites crystallizing in the anionic-deficient apatite structure, the compounds were synthesized and characterized by powder X-ray diffraction and infrared (IR) absorption spectroscopy. Electrical properties of the materials have been studied by the complex impedance spectroscopy. Correlations between electrical and structural properties are established.
