Abstract
Subsolidus phase relations in the binary system PbO-Ta2O5 were investigated by the quenching method. The following compounds were identified by X-ray diffraction patterns: PbO -2Ta2O5, PbO Ta2O6, 3PbO 2Ta2P5, 2PbO Ta2O6, 5PbO -2Ta2O5, and 3PbOTa2O5 The 1:1 compound has rhombohedral symmetry when it is prepared below 1150° C. Above this temperature, it yields an orthorhombic phase. Compounds with the same ratio of lead oxide to pentoxide exist in the systems PbO-Ta2O6and PbO-Nb2O5.
