The urea combustion method in the preparation of precursors for high-T-C single phase HgBa2Ca2Cu3O8+delta superconductors

Résumé

An alternative sol-gel route for synthesizing precursors of mercury based superconductors is presented. This route is based on urea as a combustion agent and has been applied in the synthesis of HgBa2Ca2-Cu3O8+delta (Hg-1223). Moreover, the effects of the precursor preparation on the synthesis of Hg-1223 were studied. This method is further compared with other sot-gel routes used in the synthesis of this family of compounds.
