The superconductivity of the (Tl_xBi_yPb_z)_2Sr_2Ca_2Cu_3O_w, (Tl_xBi_yPb_z)_2Ba_2Ca_2Cu_3O_w, and (Tl_xBi_yPb_z)_2Ba_1Sr_1Ca_2Cu_3O_w systems was studied. The critical temperature (T_c) of the systems was determined to be a function of the intended chemical composition of (Tl_xBi_yPb_z). The superconductive compounds with the maximum T_c of 93 K were found in the wide region in the (Tl_xBi_yPb_z)_2Sr_2Ca_2Cu_3O_w system, those with the maximum T_c of 102 K were also found in Bi-Tl region in the (Tl_xBi_yPb_z)_2Ba_1Sr_1Ca_2Cu_3O_w system and those with the maximum T_c of 110 K were observed in the Tl region in the (Tl_xBi_yPb_z)_2Ba_2Sr_2Ca_2Cu_3O_w system.
