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.

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.
