Sodium Dichromate
Appearance:
Noncaking crystalls of light orange to dark red colour.Empirical formula:
Na2Cr2O7.Used in:
· Tannery and fur industry for leather and fur tanning;
· Chemical industry for producing non-organic pigments, catalyzers and other chrome-containing elements;
· Textile industry for fabric pickling;
· Other industries in passive mixtures content, in antifreeze liquid for engines, acetylene cleaning and chemical reagents.
Sodium Dichromate is a strong oxidising agent and a source in
preparing chromium based derivatives. It is used in metal passivation and finds
applications across diverse industries including pigments and coatings, screen
printing in photographic engraving, electroplating, pyrotechnics and
explosives.
As a wood preservative, Sodium Dichromate protects wood from
termites and fungi while in metal treatment it works as a corrosion inhibitor.
It is also used in pigment preparations like chrome oxide green and lead
chromate.

storage on wood floors
- Remove
and dispose of any spilled dichromate, don’t return to original container
- Protect against physical damage by
handling vehicles like forklift or crane hooks, so as to prevent damage to
bags
