Li3Fe1.2Sc0.75Y0.05(PO4)3 compound has been synthesized by solid state reaction method. The results of X-ray diffraction (XRD) investigation have shown that synthesized powders belong to monoclinic symmetry (space group P21/n) with Z = 4 formula units in the unit cell. For the study of electrical properties ceramic samples were prepared. For measurements of electrical impedance in the frequency range 10 Hz – 1 MHz two and four probe methods were used. Coaxial line was used for the investigation of impedance spectra in the frequency range from 1 MHz to 3 GHz. The electrical properties of the ceramics were studied in the temperature interval from room temperature (RT) to 600 K. The Mössbauer spectra were measured in the temperature interval (10 – 600) K.
