Sodium dichromate is the inorganic compound with the formula Na2Cr2O7. Usually, however, the salt is handled as its dihydrate Na2Cr2O7·2H2O. Virtually all chromium ore is processed via conversion to sodium dichromate and virtually all compounds and materials based on chromium are prepared from this salt. In terms of reactivity and appearance, sodium dichromate and potassium dichromate are very similar. The sodium salt is, however, around twenty times more soluble in water than the potassium salt (49 g/L at 0 °C) and its equivalent weight is also lower, which is often desirable.
Sodium dichromate is highly corrosive in nature and is a strong oxidizing agent. This substance is usually used to produce other chromium compounds but is also used for drilling muds, metal treatments, wood preservatives, production of dyes and organic chemicals, and as a corrosion inhibitor.
Sodium Dichromate Uses
Apart from its importance for the production of other chromium products, sodium dichromate also has many uses as an ingredient in the production of the following materials:
Metallic Finish - it helps to prevent corrosion, making it easier to clean the metallic surfaces and allows the paint to stick.
Organic products - used as oxidizers for the production of vitamin K and wax.
Pigments - used in making inorganic chromate pigments where it produces a range of light-stable colors. Some grades of chromate are used for the prevention of corrosion in undercoats and primers.
Ceramics - used to produce colored glass and ceramic glaze.
Textiles - used as a mordant in the acidic dyes to improve color-fast properties.
Used in chromium sulfate production.
