Abstract The changes in volume of superconducting high-T c (2223) phase of the high-temperature superconductors (HTSC) with nominal composition Bi3.2Pb0.8Sr4Ca5Cu7O x are studied by magnetic susceptibility during soaking of material in water and more aggressive aqueous solutions. The apparent volumes of the 2223 superconducting phase after long-term (168 hr) soaking in H2O, NaCl(aq), and NaOH(aq) decreased to 22%, 17%, and 57%, respectively. The atomic absorption analysis of resulting solutions showed high amounts of Sr2+ and Ca2+ in H2O and NaCl(aq) and lower amounts of Sr2+ and Ca2+ in NaOH(aq). The highest content of Pb2+ and Cu2+ was detected in NaOH(aq).
