Abstract

Changes of magnetic susceptibility and electrical resistivity of ceramic superconductors of nominal composition YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-y</sub> and Bi<sub>1.4</sub>Pb<sub>0.6</sub>Sr<sub>2</sub>Ca<sub>2</sub>Cu<sub>3.6</sub>O<sub>x</sub> observed during their soaking in water are reported. It was found that the YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-y</sub> superconductor is destroyed in few minutes by boiling water. At lower temperatures the hydrolysis reduces the volume of the superconductive phase, as seen from the susceptibility measurements. Reaction of Bi<sub>1.4</sub>Pb<sub>0.6</sub>Sr<sub>2</sub>Ca<sub>2</sub>Cu<sub>3.6</sub>O<sub>x</sub> with water causes a decrease of the relative volume of both superconducting phases at a rate substantially higher for the high temperature one (<i>T</i><sub>c</sub> = 110 K).
