  The one-pot method focuses on the reduction of the number of steps or
chemical reactions in the synthesis of materials, and it is very appealing in
terms of sustainability. In addition to this point of view, superconductors are
desired materials due to their unusual properties, such as the zero resistivity
and the perfect diamagnetism. One-pot, Thus, in this work, we described the
one-pot synthesis of YBa2Cu3O7-{\delta} superconducting ceramic. In just two
steps and a few hours, a polymer composite solution was prepared, which
originates a powder after burning the polymer out with pure phase and with
superconducting properties better than those produced by other techniques.
