Product Application of Prussian Blue CAS#14038-43-8
Iron(III) hexacyanoferrate(II), commonly known as Prussian Blue, is widely used as an iron-based pigment. It finds applications in paints, wallpaper printing, chemical coatings, carbon paper, and the plastics industry. It also serves as an antidote for poisoning by radioactive cesium or thallium. In metalworking and mechanical engineering, Prussian Blue is applied as a thin paste on metal surfaces to evaluate the precision and quality of contact or scraped surfaces.
