Ammonium Dichromate

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.


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.
