Formation of the HgBa2Ca2Cu3O8+δ superconducting materials critically depends on the used Ba2Ca2Cu3Ox precursor. On this basis, the influence of precursor on the synthesis and properties of Hg-based superconductors has been examined. For comparisons two methods we synthesized precursors separately by sol-gel and as well as ordinary solid-state reaction methods (SSRs). The results showed that the superconductors have been prepared by sol-gel route with an excellent homogeneity and high T c.
