Texturadas superconductive ceramic united pieces of TrBa2Cu3O7, where Tr means rare Earth or Yttrium, and process of union based on laminae of Ag like flux. A new process of manufacture of superconductive unions between two superconductive ceramic pieces has been developed in which the flux is a lamina of silver with a determined good thickness. The typical composition of the superconductive ceramics will be TrBa2Cu3O7-Tr2BaCuO5, where Tr means rare Earth or Yttrium. This process allows to make ceramic products superconductors with complex forms in which the currents critics through the unions remain as high as those of the original ceramic before being united.
