Prussian blue, a blue-coloured pigment, has found a wide application in various branches of production, including such industries as construction and transport, where Prussian blue is applied as a coloured coating, and also in agriculture and medicine. A typical technological process for production of Prussian blue includes nucleation, enlargement of formed crystals, aggregation of formed crystals, and, finally, recrystallization followed by further oxidation, rinsing of impurities and drying. A typical technological process for production of Prussian blue is observed, its features are studied, and the influence of chemical components on the properties of the obtained pigment are examined. Recommendations on the mole ratio and concentrating of chemical components are given. The pigment produced by the given recommendations is superior in quality to foreign counterparts.
