Niobium oxide cluster ions are produced by a laser-induced plasma source. The cluster distribution, collision-induced dissociation (CID), and cluster reactivities are studied using a triple-quadrupole mass spectrometer. CID experiments on the cluster ions Nb3O7-9+, Nb4O9-11+, and Nb5O12+ reveal that their building blocks are Nb2O5, NbO2+, NbO3, Nb3O7+, O, and O2, whereby the cluster ...

Chromium(IV) oxide - Wikipedia

Chromium dioxide or chromium(IV) oxide is an inorganic compound with the formula CrO 2.It is a black synthetic magnetic solid. It once was widely used in magnetic tape emulsion. With the increasing popularity of CDs and DVDs, the use of chromium(IV) oxide has declined.However, it is still used in data tape applications for enterprise-class storage systems.

Structure, electronic and magnetic properties of Ca-doped ...

The work is important to get better understanding of effects produced by a Ca dopant upon the structural, electronic and magnetic properties of chromium oxide. Calculated magnetic states as a function of volume for pure α-Cr 2 O 3 material demonstrate the necessity of using an intra-atomic interaction for the strongly correlated electrons, i.e. DFT+ U approach.

Optical and structural properties of chromium impurities ...

In this work, the optical properties of the gallium–niobium oxide doped with chromium ions were investigated. The samples were obtained by wet chemical and solid-state methods, investigated by X-ray powder diffraction and the data were refined by Rietveld methods. The morphology was determined by scanning electron microscope (SEM) images.

Chromium(III) oxide - Wikipedia

Chromium(III) oxide is a precursor to the magnetic pigment chromium dioxide, by the following reaction: Cr 2 O 3 + 3 CrO 3 → 5 CrO 2 + O 2. Along with many other oxides, it is used as a compound when polishing (also called stropping) the edges of knives, razors, surfaces of optical devices etc. on a piece of leather, balsa, cloth or other ...

Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...

CrNbO 4 crystallizes in the rutile structure with space group P4 2 /mnm .Both chromium and niobium atoms distribute randomly at 2a Wyckoff position and oxygen atoms occupy the 4f position. Rietveld refinement of CN-SSR sample was carried out (S.G. P4 2 /mnm) and the profile is shown in Fig. 1 along with the unit cell structure (inset of Fig. 1).The refined atomic coordinates, isotropic ...

Chromium Plansee

Chromium is a lightweight blue-silvery white metal. The name chromium comes from the Greek "chroma" and means color.Thanks to its very high corrosion resistance against many different acids and bases as well as hot gases, chromium is a popular material for all types of protective coating. In combustion equipment, chromium is used as a wear-resistant coating to increase the service life of ...

Niobium - Wikipedia

Niobium, also known as columbium, is a chemical element with the symbol Nb (formerly Cb) and atomic number 41. Niobium is a light grey, crystalline, and ductile transition metal.Pure niobium has a hardness similar to that of pure titanium, [contradictory] and it has similar ductility to iron.Niobium oxidizes in the earth's atmosphere very slowly, hence its application in jewelry as a ...
