Synthesis of Hg₂Sr_2-xBa_xCa₂Cu₃O₁₀ Superconductor and Study the Structure and Electrical Properties

Abstract:

Compound Hg₂Sr_2-xBa_xCa₂Cu₃O₁₀ high temperature superconductor looks like (HTSC) has been prepared as a pellet by two step solid state reaction with a certain substitution percentages (0.5, 1,1.5,2) of Ba compensation rate of Sr respectively using appropriate weight of pure material Hg₂O₃, Sr(NO₃)₂, Ba(NO₃)₂, CaCO₃, and Cu(NO₃)₂ proportional to their molecular weight. XRD used for study structure properties, a computer program was used to calculation of spike dimensions the lattice parameters a, b and c shows Tetragonal, Electrical resistivity at x= 1.5 of Ba are obtained when the best value of Tc= 142 K.
