(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.
