Notes:
Li-doped Bi2Sr2Ca2Cu3O10 (2223) whiskers of single crystals with several millimeters length have been successfully prepared and it is revealed that Li-doping is effective for increasing critical temperature (Tc) of the 2223 phase. By annealing Bi2Sr2CaCu2O8 (2212) whiskers in a calcined powder with a composition of Bi2Sr2Ca4Cu6Pb0.5LixOy (x=0.2, 0.3) only within the very narrow temperature region, the conversion from the 2212 phase to the 2223 phase and Li-doping are achieved at the same time. The Tc value of the Li-doped 2223 whiskers (108.1 K) is reproducibly 1.1 K higher than that of undoped 2223 whiskers prepared by the same method using a calcined powder without Li.
