Abstract
In this work we prepare (Hg,Re)-1223 superconducting samples using the acry lamide gelification for obtaining nanoparticles of precursor phase of mercu ry-cuprates such as "Re(0.25)Ba(2)Ca(2)Cu3O(x)''. This chemical method is f ast, cheap, reproducible and easy to scale up. Also, we demonstrate that so l-gel processing is a more efficient than solid state reaction for obtainin g the superconductor phase. Finally, diagram of Pressure of synthesis versu s. 1/T are shown and discussed.
