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.

용도
Prussian blue (KFe(Fe(CN)6)) is an intense reddish blue pigment with
fairly good properties. It is used as a coloring pigment in many types of
paint systems and is also used in the production of lead chrome greens.
정의
The most common and best-
known name for blue iron ferrocyanide (iron blue)
pigments made by a variety of procedures.
Origin
Ferric hexacyanoferrate(II), known as Prussian blue, has the empirical formula Fe4[Fe(CN)6]3. It was probably synthesized for the first time by the paint maker Diesbach in Berlin in 1704, and it was one of the first synthetic pigments. A number of different, even if chemically related compounds, are named Prussian blue. Here this term refers only to insoluble ferric hexacyanoferrate(II)[1].
