Abstract:

Phase relations in the system PbO-GeO2 have been determined using the quenching technique. Five compounds were detected with compositions as follows 4PbO.GeO2, 3PbO.2GeO2, PbO.GeO2, PbO.2GeO2, and PbO.4GeO2. The 32 and 11 compounds melt congruently at 744 and 799 C respectively. The 41 compound melts incongruently at 726 C to PbO plus liquid, whereas the 14 compound melts incongruently to GeO2 plus liquid at 790 C. The 12 compound has a very narrow temperature range of stability between 707 and 730 C. Author
