Phases Bi2Sr2CaCu2Ox (2212) and Bi2Sr2Ca2Cu3Ox (2223) were grown by a cryst
allisation of the Bi-Sr-Ca-Cu-O glass. The crystallisation was carried out
between 820 degreesC and 879 degreesC. Both normal and superconducting prop
erties were influenced by the conditions of crystallisation. Very short ann
ealing time was sufficient to obtain superconducting phases. Appearance of
2223 phase as a result of only a few minutes' annealing been observed.
