Abstract
A pressure-temperature (P-T) section of the phase equilibrium diagram for Nb2O5 has been determined. Four single phase regions, H-Nb2O5, B-Nb2O5, and two L-Nb2O5 areas, were characterized by x-ray powder diffraction data. The superstructure of L-Nb2O5 was indexed on the basis of similarities to the known superstructures of L-Ta2O5 and confirmed with single crystal electron diffraction data. The correct unit cell is orthorhombic with a = 6.168, b = 29.312 , c = 3.938 A, with the b axis 8 times the subcell (8 X 3.664 A).
