摘要：
An experimental study of the PbO-MgO-SiO2 system has been carried our using high-temperature equilibration and quenching techniques, followed by electron probe X-ray microanalysis (EPMA), The phase equilibria were determined in the temperature range from 973 to 1673K. Nine primary phase fields have been investigated in this system, including three monoxides (PbO, MgO, and SiO2), five binary compounds (MgSiO3, Mg2SiO4, PbSiO3, Pb2SiO4, and Pb4SiO6), and one ternary compound Pb8Mg(Si2O7)(3). Two other ternary compounds, PbMgSiO4 and PbMgSi3O8, were observed in some experiments: however, further experiments indicated that these two compounds are unstable in the temperature range investigated.
