Phase equilibria in the system niobium pentoxide - boric acid

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1966
The phase-equilibrium diagram for the system Nb2O5-B2O3 was determined experimentally using the quenching technique and examining the samples by optical microscopy and x-ray powder diffractometry. The system contains one binary compound of approximate composition "3Nb2O5 · B2O3," which melts incongruently at about 1150 °C to H -Nb2O5 and B2O3-rich ...
