Abstract
The crystal structure of Bi-2212 phase was studied by transmission ele ctron microscopy. Two Bi-2212 specimens with different Sr/Ca ratios ha ve the same displacive incommensurate Bi modulation vector q approxima te to 0.21 b + c* but exhibit different superconducting critical temp eratures T-c. Typical structural disordering (stacking faults, Bi-laye r delineation effects, a-b plane misorientation) was found.
