Description and Uses

Iron blue is chemically referred to as ferric ammonium ferrocyanide Fe(Fe(CN)6)3. This material is generated through the reaction of sodium ferrocyanide and ferrous sulfate in the presence of ammonium sulfate. Pigments prepared with sodium or potassium salts are called ferric ferrocyanide.

Iron(III) hexacyanoferrate(II) is uses extensively as an Iron Oxide dye. Prussian blue is used as a paint and wallpaper printing, chemical coatings, carbon paper and in the plastics industry. as an antidote for poisoning with radioactive cesium or thallium. In the metalworking and mechanical engineering Prussian blue is thinly applied as a paste on metal surfaces in order to assess the quality scraped surfaces can.
