Potassium Ferrocyanide (CAS 14459-95-1), commercially known as Yellow Prussiate of Potash, is a lemon-yellow crystalline inorganic complex primarily utilized as a highly effective anti-caking agent in food-grade salt and industrial road salts. This Tetrapotassium hexacyanoferrate compound functions as a crystal modifier that prevents the agglomeration of sodium chloride crystals in Potassium hexacyanoferrate(II) treated bulk supplies, while also serving as a critical raw material for the production of Iron Blue pigments (Prussian Blue) and in case-hardening processes for steel. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside standard technical documentation, including MSDS, TDS, COA.

Product Description
Potassium ferrocyanide has the chemical formula K4[Fe(CN)6], aka Yellow blood salt, potassium hexacyanite(II), a yellow crystalline powder, is a stable and low-toxicity ferrocyanic complex known to the public, which is widely used in the production of pigments, paints, inks, food additives, erythrocyte potassium (Potassium ferrocyanide、K3[Fe(CN)6]) and other fields.
The chemical properties of potassium ferrocyanide are relatively active, and it will decompose when exposed to acid and heat, K4[Fe(CN)6It also has reducing properties, with common oxidizing agents such as over Hydrogen oxide, chlorine, potassium permanganate, nitric acid, etc., will undergo redox reactions; In addition, K4[Fe(CN)6] and many metal ions It is decomposed The reaction produces a precipitate, most typically a dark blue precipitate with Fe(III) ions – KFe [Fe(CN)6], aka “Prussian blue”, is a dark blue pigment.
The methods of industrial production of potassium ferrocyanide in China mainly include cyanide melt method, sodium cyanide method,hydrogen cyanide and potassium hydroxide method, which are essentially the conversion of potassium ferrocyanide calcium.

FAQ - Technical & Supply Chain
-
Q:
Does Potassium Ferrocyanide (CAS 14459-95-1) release free cyanide during storage or use?
A: No, the cyanide groups in this complex are tightly bound to the central iron atom, making the compound chemically stable and non-toxic under normal industrial handling conditions; it does not release free cyanide unless exposed to strong acids. -
Q:
What is the primary function of this material in salt processing?
A: It acts as an anti-caking agent (E536) that modifies the crystal growth of sodium chloride, maintaining free-flowing properties even in humid environments.
