Phase equilibria in the system niobium pentoxide-germanium dioxide [PDF]

open access: yesJournal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1966
The phase equilibrium diagram for the system Nb2O5-GeO2 has been determined experimentally, using the quenching technique and examining the samples by optical microscopy and x-ray powder diffractometry. The system contains one compound, 9Nb2O5·GeO2, which melts incongruently at 1420 °C.
