Minor amounts are used in the production of oxalic acid from cellulose and of anthraquinone from anthracene. V2O5 is used to lower the melting point of enamel frits for the coating of aluminum substrates. FeV and VAl master alloys are preferably produced from V2O5 fused flakes due to the low loss on ignition、low sulfur and dust contents、and high density of the molten oxide compared to powder. Further uses of V2O5 are as a corrosion inhibitor in the CO2 scrubbing solutions of the Benfield and related processes for the production of hydrogen from hydrocarbons、as cathode in primary and secondary (rechargeable) lithium batteries、as UV absorbent in glass、in YVO4: Eu3+ red phosphors for high-pressure mercury lamps and TV screens、for glazes、for yellow (SnO2、V2O5) and blue (ZrO2、V2O5) pigments、as colloidal solution for antistatic layers on photographic material、and as a starting material for the production of carbides、nitrides、carbonitrides、silicides、halides、vanadates、and vanadium salts.、Vanadium(V) oxide catalyses several useful aerobic oxidation reactions、most notably in the production of sulfuric acid from sulfur dioxide. (L849)、Use Classification: Plastics -> Polymer Type -> N.a.、Plastics -> Pigments agents、Industry Uses: Not Known or Reasonably Ascertainable、Catalyst、Intermediate、Alloys、Other、Consumer Uses: Catalyst、Methods of Manufacturing: V2O5 is prepared by thermal decomposition of ammonium vanadates at 500-600 °C in an oxidizing atmosphere (air).、The principal vanadium-bearing ores are generally crushed、ground、screened、and mixed with a sodium salt、e.g.、NaCl or Na2CO3. This mixture is roasted at ca 850 °C and the oxides are converted to water-soluble sodium metavanadate、NaVO3. The vanadium is extracted by leaching with water and precipitates at pH 2-3 as sodium hexavanadate、Na4V6O17、a red cake、by the addition of sulfuric acid. This is then fused at 700 °C to yield a dense black product which is sold as technical-grade vanadium pentoxide. This product contains a minimum of 86 wt % V2O5 and a maximum of 6-10 wt % Na2O. The red cake can be further purified by dissolving it in an aqueous solution of Na2CO3. The iron、aluminum、and silicon impurities precipitate from the solution upon pH adjustment. Ammonium metavanadate then precipitates upon the addition of NH4Cl and is calcined to give vanadium pentoxide of greater than 99.8% purity.、(1) Alkali or acid extraction from vanadium minerals. (2) By igniting ammonium metavanadate. (3) From concentrate ferrophosphorus slag by roasting with sodium chloride、leaching with water、and purification by solvent extraction followed by precipitation and heating.、Production: iron-vanadium ore (calcination、water leaching、solvent extraction、precipitation、calcination)、spent oil-refining catalysts、boiler fly-ash (solvent extraction、phosphoric acid、crude (solvent extraction、hydrorefining、co-produced with yellow cake)、uranium ore (leaching、co-produced with yellow cake).、Formulations、Preparations: Grades: Commercial air-dried、commercial fused、CP、chemically pure、air-dried、CP fused.、Consumption Patterns: Vanadium compounds、principally the oxidation catalyst vanadium pentoxide、account for only 3% of vanadium consumption.、U.S. Production: 2023: 5、500、000 - <7、000、000 lb、2022: 5、2021: 4、000 - <5、2020: 4、2023: 4、239、148 lb、2022: 2、198、417 lb、2021: 3、017、319 lb、2020: 1、739、431 lb、Non-confidential 2012 Chemical Data Reporting (CDR) information on the production and use of chemicals manufactured or imported into the United States.
