Superconducting single crystals of Bi-Sr-Ca-Cu-O 2212 phase have been sucessfully grown by a directional solidification method. The maximum size of single crystal reached 19+3×mm3. The (001) plane of the crystals is parallel to the growth direction. The crystals tend to grow along the [010] direction. Back-reflection Laue pattern revealed that the large crystal is indeed one single crystal. Measurements of electrical resistivity and ac susceptibility showed that Tc(zero) of the single crystals annealed in O2 was 81.5 K.
