Abstract
We compared crystal structure, phase distribution and superconducting parameters of Bi-type high-temperature superconductors (HTSC), prepared by melting and recrystallizing during centrifugation, followed by annealing. Results obtained can be explained by the different sensitivities of the 2212 and 2223 phases of Bi-type HTSC to small deviations in stoichiometry. Stable compounds with superconducting critical temperatures up to 10 K higher than the boiling point of liquid nitrogen were prepared by recrystallizing and annealing the 2212 stoichiometric composition with partial substitution of Cu by Li.
