Introduction

Prussian Blue, that is, ferric ferrocyanide (ferric ferrocyanide) chemical formula Fe4[Fe(CN)6]3, also known as Berlin blue, Gong blue, iron blue, Mi Luo Li blue, China blue, Mi Luo Li Blue, navy blue. It is an ancient blue dye that can be used for glazing and oil painting. Prussian blue brings us a breathtaking beauty, not only a unique color, but also a precipitation texture.

Chemical properties

Dark blue powder. Insoluble in water, soluble in acid and alkali.

Use

●  Dark blue paint. Used for coloring paint, ink, painting, crayon, and finishing varnished cloth, lacquer paper, plastic products, etc.

●  Used for coloring of paints, inks, plastics and other industries and cultural and educational supplies

●  The yellow blood salt method uses the reaction of potassium yellow blood salt and ferrous sulfate in a slightly acidic solution to form a double salt of ferrous ferrocyanide, which is then oxidized with potassium sulfate chlorate to form a double salt of ferrous ferrocyanide and potassium ferrocyanide. . If the yellow blood salt sodium is used to make ferric blue, the resulting double salt should use ammonium to replace the sodium, that is, the double salt of ferric ferrocyanide and ammonium ferrocyanide is generated, so ferric blue is divided into potassium according to different raw materials. There are two kinds of iron blue and ammonium iron blue. The above double salt is filtered, rinsed, dried and pulverized to obtain dark blue iron blue pigment.
