Project at a Glance

Contents on the CD Rom

  • Sodium dichromate is also commonly referred to as sodium bichromate or sodium bichromate dihydrate and is known technically as sodium dichromate dihydrate.
  • The cleaner process of sodium dichromate production by roasting chromite with lime and leaching with sodium bicarbonate solution under the pressure of carbon dioxide was investigated.
  • Dichromates are power oxidizing agents which find applications in: Chromium source in preparing chromium compounds, Leather tanning and screen printing, Electroplating ,Pyrotechnics and explosives, Pigment preparation, Wood Preservative , Metal Treating and corrosion inhibitor, Oil drilling ,Catalyst for the chromium metal production ,Photographic engraving.
  • In the pigment industry, sodium dichromate is used to manufacture lead chromate compounds which are then used in manufacturing paints, printing inks, paper coloring, and floor coverings.
  • In oil well drilling muds, sodium dichromate is used to create soluble chromates for corrosion control and chrome lignosulfates for deflocculation and thinning agents which help control drilling mud viscosity.
  • Sodium dichromate is also used in the manufacture of photographic films, flavors, essential oils, saccharin, pharmaceuticals,9 pyrotechnics, explosives, safety matches, chrome glues and adhesives, wood stains, poison fly paper, process engraving and lithography, synthetic perfumes, chrome alum manufacture, alloys, ceramic products, depolarizers in dry cell batteries, bleaching fats and waxes.
  • Growth in demand for sodium dichromate is expected to be supported largely by increases in the need for chromic acid in the manufacture of wood preservatives.
  • Leather tanning consumption of sodium bichromate is 12 percent of the total demand. U.S. exports of leather auto upholstery continue strong, especially to Japan, Canada and Mexico.
  • Consumption of chromium chemicals has been in decline since peaking at 163 thousand tons in 1974. This is primarily due to environmental and health concerns. The trend has apparently now ceased and the current consumption level represents difficult-to-substitute applications of chrome chemicals. Over the next four years, U.S. sodium bichromate consumption is anticipated to grow modestly, at 0.5 percent annually.
