Abstract:

 The influences of the Cu substitution at Hg site in the HgOd layer, upon themicrostructure, Tc and oxygen content of Hg-1223 have been investigated. Hightemperature superconductor with a nominal composition Hg1-xCuxBa2Ca2Cu3O8 + δ forCu ( 0 £ x £ 0.5) have been prepared by the two-steps solid state reaction methodunder optimum conditions. XRD showed a tetragonal structure with a high ratio ofHg-1223 superconductor phase. Tc enhancement has been determined with the Cuconcentration was is found to be Tc = 153 K for x = 0.3, while the oxygen contentobserved variously with Cu concentration. Hg1-xCuxBa2Ca2Cu3O8+δ structure, oxygencontent and Tc behavior have been discussed.
