Resumen:
Single phase materials of Hgl.~Re~Ba2CuOy samples were obtained for 0.00 < x < 0.15. Theywere studied by thermogravimetry under controlled p(Oz) to analyze the influence of Re on theirchemical stability, oxygen nonstoichiometry and thermodynamic properties.Under and over-doped samples were obtained by changing the oxygen content. The oxygencontent was determined by neutron diffraction and thermogravimetric measurements.The role of Re on the superconducting behavior and the improvement of the chemicalstability of the Hg-1201 compounds is discussed.
