Abstract
Directionally solidified high temperature superconducting (Bi,Pb)-Sr-C a-Cu-O pure ceramics and composites were obtained using a laser floati ng zone (LFZ) apparatus. The presence of secondary non-superconducting and metallic phases as well as their solidification habit have been a nalysed. The influence of the LFZ growth conditions and the precursor composition on the microstructure of the final products was studied us ing optical and electron microscopies.
