Samples of the Bi-Te-Pb-Sr-Ca-Cu-O system with various nominal compositions were prepared by a free melt-quenching and subsequent annealing procedure. Phase formation, To, Jc, Be2 (0), and irreversibility line were investigated employing direct measurements as well as estimations by AC losses and AC
