Potassium ferrocyanide Use and Manufacturing

Potassium cyanide and ferricyanide, dry colors,tempering steel, dyeing, explosives, process engrav-ing and lithography, laboratory reagent. As an anticaking agent, our country stipulates that it can be used for table salt, and the maximum use amount is 0.005g%kg (calculated as ferrocyanide). my country GB2760-96 stipulates that it is allowed to be used as an anticaking agent for table salt. The maximum usage amount is 0.01/kg (calculated as ferrocyanide). It is often used in certain wines in Europe to remove iron and copper. Used in the manufacture of pigments, printing and dyeing oxidation additives, potassium cyanide, explosives and chemical reagents, and also used in steel heat treatment, lithography, carving, etc
