The urea combustion method in the preparation of precursors for high-T sub(C single phase HgBa) sub(2)Ca sub(2Cu) sub(3)O sub(8+I superconductors)

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 HgBa sub(2Ca) sub(2)Cu sub(3O) sub(8)+I (Hg-1223). Moreover, the effects of the precursor preparation on...

Description
Summary: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 HgBa sub(2Ca) sub(2)Cu sub(3O) sub(8)+I (Hg-1223). Moreover, the effects of the precursor preparation on the synthesis of Hg-1223 were studied. This method is further compared with other sol-gel routes used in the synthesis of this family of compounds.
