Resumen:
Bi2Sr2CaCu2O8+δ samples with -0.06 < δ <
0.16 were prepared by controlled reduction in static hydrogen atmosphere and
continuously monitored by thermogravimetry. Lattice parameters suggest that the
2212 superconducting phase is stable for δ >
0.12. ED patterns indicate that nonstoichiometry is accommodated by random
distributionof anionic vacancies along the CuO layers.
