The lower T_c of the Bi-Sr-Ca-Cu-O (BSCCO) system can be raised by more than 15 K by quenching. This characteristic has been confirmed for a stoichiometric 2212 compound. From the ac susceptibility measurement of the powdered specimens, we revealed that the observed T_c enhancement is not filamentary but has a bulk origin. X-ray diffraction study indicated that our specimens are almost single phase and the crystalline cage is not altered drastically by quenching.
