Phase relations in the ternary system were determined by solid‐state reaction, quenching, and electron microscopy of the immiscible liquid region. The limits of the stable 2‐liquid region and the approximate limits of the metastable 2‐liquid region were determined. Relations in the region of homogeneous glass formation in the system, which included the joins SrSiO 3 ‐PbSiO 3 , SrSiO 3 ‐Pb 2 SiO 4 , and SrSiO 3 ‐Pb 4 SiO 6 , were determined by quenching. The solid‐solution limits of SrSiO 3 in Pb 2 SiO 4 and Pb 4 SiO 6 and of PbSiO 3 in SrSiO 3 were established. Two new compounds were discovered, 3SrO.2PbO.SiO 2 and 2SrO.3PbO.SiO 2 , and extensive solid‐state trials permitted the compatibility triangles to be established. The accumulated data were assembled in the form of an equilibrium diagram for the system, including joins, boundary lines, and isotherms.
