Preparation of Uranium-Niobium Alloys by Bomb Reduction; PREPARATION D'ALLIAGES URANIUM-NIOBIUM PAR REDUCTION EN BOMBE

, 1959
Uranium--niobium alloys were prepared by direct reduction with calcium of urardum tetrafluoride and niobium pentoxide. The reduction of potassium oxyfluoniobate did not give satisfactory results. Alloys containing up to 20% niobium have been successfully

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 ...

Oxygen Vacancies in Niobium Pentoxide as a Source of Two-Level System Losses in Superconducting Niobium [PDF]

We identify a major source of quantum decoherence in three-dimensional superconducting radio-frequency (SRF) resonators and two-dimensional transmon qubits composed of oxidized niobium: oxygen vacancies in the niobium pentoxide which drive two-level ...

Carbothermic reduction of pyrochlore and niobium pentoxide in a transferred arc plasma : a thesis

, 1989
The carbothermic reduction of pyrochlore and niobium pentoxide was studied, with and without the addition of iron as a solvent, in an argon transferred-arc plasma with a single stationary pellet reactor system.
