Dichromates are power oxidizing agents which find applications in:
- Chromium source in preparing chromium compounds
- Leather tanning and screen printing
- Electroplating
- Pyrotechnics and explosives
- Pigment preparation
- Wood Preservative
- Metal Treating and corrosion inhibitor
- Oil drilling
- Catalyst for the chromium metal production
- Photographic engraving
In biological field, potassium dichromate is used as a fixative for used for conservation of tissue sections.
Dosage
After thorough cleaning, the stainless steel part is ready for immersion in a passivating acid bath. Any one of three approaches can be used--nitric acid passivation, nitric acid with sodium dichromate passivation and citric acid passivation. Which approach to use depends on the grade of stainless steel and prescribed acceptance criteria.
Bulletin Details
After thorough cleaning, the stainless steel part is ready for immersion in a passivating acid bath. Any one of three approaches can be used--nitric acid passivation, nitric acid with sodium dichromate passivation and citric acid passivation. Which approach to use depends on the grade of stainless steel and prescribed acceptance criteria.
More resistant chromium-nickel grades can be passivated in a 20 percent-by-volume nitric acid bath . As indicated in the same table, less resistant stainless grades can be passivated by adding sodium dichromate to the nitric acid bath to make the solution more oxidizing and capable of forming a passive film on the surface.
Another option, used in place of nitric acid plus sodium dichromate, is to increase the concentration of nitric acid to 50 percent-by-volume , The sodium dichromate addition and lit : higher nitric acid concentration both reduce the chance of undesirable flash attack.
