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 700Β°C in a low oxygen pressure range. Be
