摘要: Compound Hg2Sr2-xBaxCa2Cu3O10 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.
