Abstract

Equilibrium phase relationships for the pseudo-ternary systems Bi2O3-PbO-CaO and Bi2O3-PbO-SrO at 873K and 1073K in air have been studied mainly by the powder X-ray diffraction method. At 1073K, the regions of liquid or liquid plus solids were determined in the both systems. In these systems we found two new solid solutions (α and β) and two new compounds (Bi8Pb7Ca2Ox and Bi8Pb9Sr3Ox). Two new compositions Bi3Ca2Ox and Bi11Pb4Ox were proposed instead of Bi10Ca7O22 and Bi3PbOx already reported, respectively.
