Resumen:
We studied mass evolution of YBa2Cu3O7-d powder samples under oxygen atmosphere at different constant temperatures. We followed the change in oxygen content d (0 1) by samples mass variation, using a thermogravimetric analysis system. We found the optimal oxygenation temperature to be around 345 °C. We also found excellent conditions in a fast-absorption mode around 690 °C. Finally, traces of the tetragonal-orthorhombic structural phase transition in this material are observed.
