FAQ - Technical & Supply Chain
-
Q:
Are Sodium Ferrocyanide and Sodium Hexacyanoferrate(II) the same salt?
A: Yes. Both names refer to tetrasodium hexacyanoferrate(II), associated with CAS 13601-19-9 and commonly traded in hydrated form. It is not sodium ferricyanide or free cyanide. Confirm the hydrate and assay basis in the quotation. -
Q:
What is Sodium Ferrocyanide used for?
A: It is mainly used as an important raw material for pigments, tanning, smelting and chemical industries, including iron blue and red blood salt production. It is also used in metal surface anti-corrosion treatment, carbon steel carburizing, as an oxidizing agent, chemical reagent, snowmelting additive and anti-caking agent. -
Q:
Which specifications should be agreed for industrial Sodium Ferrocyanide?
A: Specify assay and reporting basis, water or hydrate content, free cyanide where required, chloride, sulfate, insoluble matter, iron and relevant heavy metals. Technical and regulated grades are not interchangeable, so state the required grade and test methods. -
Q:
What safety and regulatory points apply to Sodium Ferrocyanide?
A: Although the material is a ferrocyanide complex rather than free cyanide, it is still transported under UN 1588 and must be handled with appropriate controls. Follow local requirements for incompatibilities, exposure limits, waste management and regulatory suitability. -
Q:
What hydrate and physical data should be confirmed for Sodium Ferrocyanide?
A: Sodium ferrocyanide is commonly supplied as a pale yellow crystalline solid, often as the decahydrate, with density about 1.458 g/cm3 and water solubility around 10.2 g/100 mL at 10 C. The decahydrate starts losing water near 50 C, becomes anhydrous near 81.5 C and decomposes around 435 C, so the hydrate state and assay basis should be stated.
