Popis:	The TSFZ method has been used to grow crystals of the Bi-oxide superconductor of the Bi-n = 1 structure. The investigated compositions are Bi2Sr2CuO6+z, Bi2.3Sr1.7CuO6+z, and Bi2+xSr1.6- LayCuO6+z (x+y = 0.4). Except for the stoichiometric composition, the TSFZ experiments yield plate-like crystals of the superconducting R-phase. Superconductivity was only present in La substituted crystals and the TC could be changed by annealing procedures. A maximum TC = 29 K is found for Bi2.0Sr1.6La0.4CuO6+z.
