Application:
Sodium Ferrocyanide Mainly
used as important raw material for pharmaceutical, pigment, tannage,
metallurgy and chemical industries. used in producing iron blue and
potassium ferricyanide, surface corrosion protecting for tannage and
metal, carburization treating for carbon steel, removing iron in
pharmaceutical producing. Used as oxidant, food additive, explosive
and chemical reagent. Also used as additive for preventing
agglomeration in melt snow in winter.
