The oxygen nonstoichiometry of BiL74Pbo.27SrLs~Ca2.ogCu3.o4Oy (2223 phase) was determined as a function of temperature and oxygen partial pressure under the condition that Ca2PbO4 was not formed. It was also found that PbO evaporated from the 2223 phase about 700ยฐC in a low oxygen pressure range. Be
Bi-pb-Sr-Ca-Cu-O bulk samples with nominal composition of Bil.6Pb0.4Sr2Ca3Cu4Oy (2234) were prepared by a melt casung method. The melting process was carried out on two different powders; one consisting of the precursor materials, and one in which the precursor had been calci,r,d.Th~-~ffects of the
