Applicazioni

Sodium dichromate is used as a strong oxidizing agent in organic synthesis. It is used in metal finishing as an aid of corrosion resistance, manufacture of inorganic chromate pigments and in the preparation of colored glass and ceramic glazes. It is used as a mordant for acidic dyes to improve their color-fast properties and as a corrosion inhibitor in undercoats and primers.

Note
