Project at a Glance Contents on the CD ROM
  • Ammonium Dichromate is an odorless, bright orange to red, crystalline (sand - like) solid. It is used in dyeing textiles, as a pigment and oxidizing agent, and in metal treatment.
  • Ammonium dichromate is produced by a crystallzation process involving equivalent amounts of sodium
    dichromate and ammonium sulfate.
  • Ammonium dichromate is sometimes known as Vesuvian Fire, because of its use in demonstrations of tabletop "volcanoes". It has been used in pyrotechnics and in the early days of photography.
  • Cr(VI) compounds include: ammonium dichromate ((NH4)2Cr2O7); calcium chromate (CaCrO4); chromium trioxide or chromic acid (CrO3); lead chromate (PbCrO4); potassium chromate (K2CrO4); potassium dichromate (K2Cr2O7); sodium chromate (Na2CrO4); strontium chromate (SrCrO4); and zinc chromate (ZnCrO4).
  • It is also used as a mordantfor dyeing pigments, in the manufacturing of alizarin, chrome alum, leather tanning and oil purification.
  • Hexavalent chromium is a toxic form of the metal chromium. It is widely used in many industries.
  • Major industrial uses of Cr(VI) compounds include: chromate pigments in dyes, paints, inks, and plastics; chromates added as anticorrosive agents
    to paints, primers, and other surface coatings; and chromic acid electroplated onto metal parts to provide a decorative or protective coating.
  • Cr(VI) can also be formed when performing “hot work” such as welding on stainless steel, melting chromium metal, or heating refractory bricks in kilns. In these situations the chromium is not originally hexavalent, but the high temperatures involved in the process result in oxidation that converts the chromium to a hexavalent state.
