Whiskers of the high {ital T}{sub {ital c}} Bi{sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub 10} (2223) phase have been prepared by annealing Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} (2212) whiskers in a Bi{sub 2}Sr{sub 2}Ca{sub 4}Cu{sub 6}Pb{sub 0. 5}O{sub {ital x}} powder. By the same method, single-crystal sheets of the 2212 phase have also been converted to the 2223 phase, resulting in 2223 sheet crystals as large as approximately 1 mm{sup 2}. Although the original sample outlines are retained after the phase conversion, the smooth surfaces were lost due to contact with the powder during annealing. A zero-resistance temperature of 107 K and a maximum {ital J}{sub {ital c}} value of 7.3{times}10{sup 4} A/cm{sup 2} at 77 K in a zero magnetic field were obtained for the 2223 whisker.
