Abstract: Heat pollution could be through decreasing the electrical resistance of wire conductors. The main approach of this research is to modify the superconducting ceramic. The composite samples consisting of YBa2Ca2Cu2.8(Ag, Hg)0.2 O7-δ superconductor ceramic and epoxy have been prepared. The sander four probe techniques and contactless induction based on Meissner effect were used to study the superconducting properties of sintered ceramic and composite samples. The results showed that in all composite samples which were prepared by the addition of the ceramic superconducting powder as filler to the epoxy polymer, there was no decrease in the Tc of ceramic superconductor precursor filler; a very slight change was observed. The partial replacement of Cu ion by either Ag or Hg ions was found to modify the superconductive nature. Also, the advantage of using composite material is providing a high efficiency and low loss, which have not impeded the development of its applications.
