Abstract
An assessment of the phase stability of lead-doped Bi-2223, (Bi,Pb)-2223, as a function of temperature and partial pressure of oxygen, p(O 2), derived from equilibration and electromotive force studies carried out by numerous groups of investigators is presented. The data obtained from this assessment, coupled with additional more recent data from our laboratory, can be used to estimate the stability of this promising high-Tc bismuth cuprate system in the temperature range from 650 to 870°C and for oxygen partial pressures ranging from 10 −5 to one atm. For oxygen contents above pO 2=0.02 atm, the stability boundaries are reasonably well known. For smaller pO 2, discrepancies are found.
