- Recommended Applications
- Pigment manufacturing: Pigments include chrome yellow and orange, molybdate orange, zinc yellow, chrome green, chromium oxide green, hydrated chromium oxide green, barium chromate, and others.
- Metal treating: The dip-cleaning of certain metals in solutions containing sodium dichromate and acid results in the metal having a uniform, untarnished surface that is protected by a corrosion-resistant film.
- Oil-well drilling: The reaction products of sodium dichromate with various lignosulfonates and lignites are used as treating agents in drilling mud systems.
Other applications include use as a powerful oxidizing agent in many organic syntheses, in the preparation of colored glasses and glazes, and in the preparation of other chromium compounds.
