GENERAL 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.

HEALTH AND SAFETY PRECAUTIONS:

Sodium dichromate is a hexavalent chromium compound, and contact with it, either in the solid or solution form, should be avoided. .

In case of contact, flush with water; for eyes, give prolonged irrigation with water, and get medical attention immediately. For detailed information, consult our Material Safety Data Sheet (MSDS), which is available upon request.
