Bi2.2Sr1.8Ca2Cu3O 10+δ high quality crystals with x=0.2 were grown. The crystals were characterized by X-ray diffraction and DC susceptibility measurements confirming Bi2223 to be the major phase. The results are compared with those of Bi2223 with x=0.1, revealing that the Bi/Sr substitution ratio does not affect Tc. The doping dependences of the anisotropic normal state susceptibilities χc(T)(Hc) and χab(T)(H⊥c) show that dimensionality of Bi2223 decreases in underdoped regime.
