The system niobium pentoxide-phosphorus pentoxide

Journal of Solid State Chemistry, 1970
Abstract A partial phase diagram of the system Nb 2 O 5 P 2 O 5 has been determined experimentally, using the quenching technique and identifying the phases by X-ray powder diffractometry. The major phase, NbPO 5 , has a melting point above 1650°C.

Synthesis of niobium pentoxide aerogels

Journal of the Chemical Society, Chemical Communications, 1990
Niobium pentoxide (Nb2O5) was successfully synthesized as an aerogel which, after calcination at 773 K for 2 h, had a Brunauer–Emmett–Teller (BET) surface area of 190 m2 g–1 and acidity comparable to that of niobic acid.

Thermoluminescence of Alpha Niobium Pentoxide

Journal of the American Ceramic Society, 1962
Alpha niobium pentoxide (Nb2O5) was investigated for thermoluminescence after exposure to ultraviolet or Co60 gamma radiation. Unirradiated alpha -Nb2O5 did not exhibit thermoluminescence. After exposure to ultraviolet radiation for 20 hr, peaks were found in the glow curve at 240 and 120°C.

Synthesis of niobium pentoxide gels

Journal of Non-Crystalline Solids, 1986
Abstract Niobium pentoxide gels can be obtained by the two classical ways already known for silica, namely destabilisation of a sol and alkoxide's hydrolysis. Owing to the lack of reproducibility of the first route and to the high cost of niobium alkoxides, two other processes are proposed.
