Bulk polycrystalline Hg 0.6Tl 0.4Ba22Ca 02(Cu01-xAg0x)03 O 8+δ compound samples with x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6 and 0.7, are synthesized by solid state reaction process. Study identi􀏐ies Silver substitution on superconductivity behavior. Structural speci􀏐ications are deliberated by using X-ray powder pattern, the high temperature phase superconductor (Hg-1223) of the tetragonal structure didn't change with the partial replacement of Cu+2 by Ag+1 ions, lattice parameters a, c ,c/a are established to vary as function of Ag- substitution. Transition temperature (Tc) has been calculated using technique of four-probe to measure electrical resistivity. Transition temperature at zero resistivity T c(offset) decreases from 117 to 86 K with increasing Ag. In addition, dielectric properties (dielectric constant and loss) are characterized directly by relating with Ag concentration.
