Potassium dichromate Potassium dichromate

Formula CAS
Cr2K2O7 7778-50-9


Chrome is a steel-gray, lustrous metal used in the manufacture of chrome-steel or chrome-nickel-steel alloys (stainless steel) to increase resistance and durability of other metals. It is the fourth most common material in the earth's crust and the most common cause of occupationally induced allergic contact dermatitis, particularly in men. It has been used to prepare chromic acid for cleaning glassware and etching materials. It is used as an ingredient in cement in which it retards the setting of the mixture and improves its density and texture. This usage commonly causes contact dermatitis in construction workers. It is used in photography as an oxidizing agent.
