Kinetics of the vapor phase chlorination of niobium

tion of pure niobium metal involving the hydrogen reduction of pure niobium pentachloride lends itself to a continuous operation which, for commercial application, has several advantages over a batch operation. A recent patent by Jenkins and Jacobsen (23) outlines such a method for production of very pure niobium as well as tantalum or tungsten.

Electrochemical Synthesis of Ceramic Materials. 3

Anodic dissolution of Nb foil in an electrolyte solution containing liquid NH 3 and NH 4 Br produces an insoluble precursor that can be calcined to yield phase-pure NbN. Infrared spectroscopy is consistent with a precursor having the general formula NbX n (NH 2) 5-n.pNH 3.By changing the calcination conditions, the phase of the resulting NbN powder can be varied.

Niobium Incorporation into CsPbI2Br for Stable and

All-inorganic perovskites are attracting increasing attention due to their superior thermal stability than that of the traditional CH3NH3PbI3, while their inferior phase stability in ambient conditions is still an unsolved issue. Here, for the first time, we report the incorporation of niobium (Nb5+) ions into the CsPbI2Br perovskite. Results indicate that Nb5+ can effectively stabilize the
