abstract
Nearly monophasic 110 K (n = 3 phase) superconductor in the BiPbCaSrCuO system has been prepared starting from compositions of Bi0.7Pb0.3CaSrCu2Ox, Bi1.5Pb0.5Ca2Sr2Cu3Ox, and Bi1.84Pb0.34Ca2.03Sr1.91Cu3.06Ox. Attempts have been made to prepare the Bi1.5Pb0.5Ca2.6Sr2.4Cu4.09Ox (n = 4 phase) and the n = 3 phase by hot pressing and the results will be discussed. 1989.
