Chromium dioxide or chromium(IV) oxide is a synthetic magnetic substance once widely used in magnetic tape emulsion. Chromium (IV) oxide has a tetragonal unit cell with a rutile-type structure. Chromium(iv) oxide, CrO2, is unique among the rutile-type transition metal dioxides, exhibiting ferromagnetic (Tc = 395 K) and metallic properties. CrO2 is also one of the simplest known half-metals and crystallizes into the rutile structure at ambient conditions, a structure commonly found in many metal dioxide. CrO2 is not a stable Cr–O phase under normal conditions, and the magnetic properties of chromium oxides are highly sensitive to changes in stoichiometric composition. CrO2 is the only ferromagnetic phase among all the oxides of chromium. Magnetic-tape-grade chromium dioxide ha s been prepared by a single step synthesis employing hydrothermal decomposition of commercially available CrO3. Among the magnetic materials being actively investigated for their potential use in such devices CrO2 is one of the most attractive because it is a halfmetal fully spin polarized at the Fermi level with a Curie temperature well above room temperature and a magnetic moment of 2 μB per formula unit. Chemical vapor deposition CVD technique was discovered in the late 1970s, and perhaps is still the most effective way for epitaxial CrO2 ﬁlm fabrication. Chromium dioxide is a metastable phase that can only be prepared at high pressure conditions; preparation at low pressure requires special chemical reactions involving a special precursor, special substrates and techniques. Chromium oxide coatings are chemically inert, have high mechanical strength, hardness and good optical characteristics; therefore, they have been widely used in many applications including corrosion protection, wear resistance, electronics, and optics. Chromium dioxide is recently of considerable interest due to its attractive potential for use in spintronic heterostructures. Transition metal oxides exhibit a wide range of physical, chemical, and structural properties and are important in various technological applications, including electronic materials, catalysis, and corrosion inhibition.	*Introduction* Chemistry, Geochemistry, and Geology of Chromium and Chromium Compounds Chromium Dioxide Powder Chromium Oxide Green Chromium Dioxide (CrO2) Half-Inch Media Chromium (IV) oxide Msds Anhydride chromique Chromium Oxide Green H Cement Chromium dioxide Chromium (III) Oxide Chromium oxide Chromium oxide - Msds Patents Preparation of ferromagnetic chromium dioxide Ferromagnetic Chromium Dioxide Crystals Process for treating chromium dioxide Acicular ferromagnetic chromium dioxide particles Coated chromium dioxide particles Method for Making Ferromagnetic Chromium Dioxide Phosphorus - modifies ferromagnetic chromium dioxide Preparation of stabilized acicular ferromagnetic chromium dioxide Process for synthesis of ferromagnetic chromium dioxide Processing Preparation of Chromium Dioxide for Magnetic Recording Applications Fabrication of chromium oxide Oxidative Dehydragenation Preparation and characterization of thin ferromagnetic CrO2 films Pulsed plasma deposition of chromium oxide/ chromium-cermet coatings Specifity of silica - supported chromium - oxide catalysts A new method for the synthesis of chromium(iv) oxide at ambient pressure Technology Magnetic Domain Configurations and Huge Wall Resistivity in Half-metallic Chromium Dioxide (CrO2) Nanostructures Chromium Dioxide Near-complete spin polarization in atomically-smooth chromium-dioxide epitaxial films Interfacial Microstructure of ChromiumOxide Coatings Nanoscale ferromagnetic chromium oxide film from gas-phase nanocluster deposition Suppliers Chromium Dioxide Suppliers Chinese Suppliers Indian Suppliers	Studies Bistable memory effect in chromium oxide junctions Characterizing crystalline chromium oxide thin film growth parameters Cyclic Oxidation Resistance of Rare Earth Oxide Gel Coated Fe-20Cr Alloys Electronic Structure of Chromium Dioxide surface Epitaxial Growth of CrO2 Thin Films on TiO2(110) Surfaces Lanthanum Chromium Oxide Catalyst Microstructural characterization of chromium oxide thin films grown by remote plasma assisted pulsed laser deposition Morphological and structural characterization of CrO2/Cr2O3 films grown by Laser - CVD Phase control of chromium oxide in selective microregions by laser annealing Potential phase control of chromium oxide thin films KrF pulsed laser deposition of chromium oxide thin films from Cr8O21 targets Ultraviolet photoelectron spectroscopy of the chromium dioxide negative ion High Pressure Structure of Half-Metallic CrO2 Uses Chromium Oxide Catalysts in the Dehydrogenation of Alkanes Application of Novel Chromium Dioxide Magnetic Particles to Immunoassay Development Chromite — A Cost-Effective Refractory Raw Material Catalytic Performance of Chromium Oxide Company Profiles and Consultants Company from China Another company from China Consultant from USA Consultant from New York Consultant from India Consultant from California Consultant Reports Inorganic Chromium Compounds Extrinsic giant magnetoresistance in chromium IV oxide, CrO2 Final Report Health Effects Reduction of Chromium oxide in Stainless Steel Slags TDK Corporation - Company Profile, Information, Business Description, History, Background Information on TDK Corporation Orbital Selective Mott Transition in 3D AND 5F Materials Order the CD ROM Today
