Abstract: The present study the partial substitution of copper with nickel on of HgBa2Ca2 Cu3xNix O8+δ superconducting compound where x=002040608 Samples were prepared by solid state reaction method with sintering temperature 850C0 for 24h. By using Xray powder diffraction structural of the samples were studied. The XRD analysis's showed the structures a polycrystalline with tetragonal diagram with majority 1223 phase and the change of the nickel concentrations produce a change in lattice parameters of the lattice a b and c axis c/a density of mass ρm and volume fraction Vphase. Four probe apparatus was using to test the electrical resistivity to defined the critical temperature at zero resistivity Tc offset Optimum Tc offset was found from HgBa2Ca2Cu24Ni06O8+δ sample with transition temperature its equal to 137K
