The solid electrolyte powders of Li1+x+y ScxByTi2-x-y(PO4)3 (where x, y=0, 0.1, 0.2, 0.3) were synthesized by solid state reaction. The structure of all compounds was studied by X-ray diffraction from the powder. The ionic conductivity of the sintered ceramic samples has been investigated by impedance spectroscopy in the frequency range from 7·105 to 1.2·.109 Hz at temperatures up to 600 K. Two relaxation dispersions of the electrical parameters were found and analyzed in terms of bulk and grain boundary ionic transport processes
