Niobium oxide, archaically called columbium oxide, [1] may refer to: Niobium monoxide (niobium(II) oxide), NbO; Niobium dioxide (niobium(IV) oxide), NbO 2; Niobium pentoxide (niobium(V) oxide), Nb 2 O 5; In addition to the above, other distinct oxides exist general formula Nb 3n+1 O 8n−2 where n ranges from 5 - 8 inclusive, e.g. Nb 8 O 19 (Nb ...
Niobium is used to make the high voltage wire of the solar corona particles receptor module of the Parker Solar Probe. [125] Niobium is a constituent of a lightfast chemically-stable inorganic yellow pigment that has the trade name NTP Yellow. It is Niobium Sulfur Tin Zinc Oxide, a pyrochlore, produced via high-temperature calcination. The ...
The oxide for example, arises when niobium metal is oxidised in air. [10] The oxidation of niobium dioxide, NbO 2 in air forms the polymorph, L-Nb 2 O 5. [11] Nano-sized niobium pentoxide particles have been synthesized by LiH reduction of NbCl 5, followed by aerial oxidation as part of a synthesis of nano structured niobates. [citation needed]
Vanadium(V) oxide or vanadium pentoxide is the most common, being precursor to most alloys and compounds of vanadium, and is also a widely used industrial catalyst. [29] Niobium forms oxides in the oxidation states +5 (Nb 2 O 5), [30] +4 (NbO 2), and the rarer oxidation state, +2 . [31]
Lithium niobate (Li Nb O 3) is a synthetic salt consisting of niobium, lithium, and oxygen. Its single crystals are an important material for optical waveguides, mobile phones, piezoelectric sensors, optical modulators and various other linear and non-linear optical applications. [6] Lithium niobate is sometimes referred to by the brand name ...
Niobium monoxide is the inorganic compound with the formula Nb O. It is a grey solid with metallic conductivity. It is a grey solid with metallic conductivity. [ 1 ]
Organoniobium chemistry is the chemistry of compounds containing niobium-carbon (Nb-C) bonds. Compared to the other group 5 transition metal organometallics, the chemistry of organoniobium compounds most closely resembles that of organotantalum compounds.
Niobium dioxide, is the chemical compound with the formula NbO 2. It is a bluish-black non-stoichiometric solid with a composition range of NbO 1.94 -NbO 2.09 . [ 1 ] It can be prepared by reducing Nb 2 O 5 with H 2 at 800–1350 °C. [ 1 ]
