Silver lithium niobate Ag1-xLixNbO3 (x = 0, 0.3, 0.5 and 0.7) mixed ceramic pellets were synthesized by the by solid-state reaction and sintering method. The lattice parameters of ceramic pellets were characterized by X-ray diffraction (XRD). The prepared samples show a perovskite structure and exhibit the orthorhombic symmetry at room temperature. Frequency dependent dielectric investigations, i.e., dielectric constant, loss tangent and electrical conductivity were carried out in the frequency range 10Hz-10MHz at room temperature. http://pubs.sciepub.com/ajmse/1/3/5/ajmse-1-3-5.pdf perovskitesilver lithium niobateceramicX-ray diffraction (XRD)dielectric constantloss tangentelectrical conductivity
