| Abstract | ||
| High temperature superconductor with a nominal composition Tl2- xAgxBa2Ca2Cu3O10 + δ for (0 ≤ X ≤ 0.5) was prepared by a solid-state reaction method by Two – Step under a hydrostatic pressure 8 ton/cm² and annealing Tempereture (850 ˚C) . The best conditions to obtain samples of the mentioned compound holding with superconducting property at high temperatures. X – Ray Diffraction patterns analyses have showed a teteragonal structure, and there is an increase of lattice parameterer value C- axis with the increase of the Tc value but it was decreased with the increase of Ag dopant concentration (X≥0.3) . The partial substitution effect of the (Ag) in (Tl) metal in the compound as T12-xAgBa2Ca2Cu3O10 + δ has been investigated where X = (0.1, 0.2, 0.3) The critical temperature increased from (134K) to (146K) due to increasing oxygen content and increasing C-axis by using X-ray diffraction . | ||
