- n. A salt containing the negative tetravalent radical Fe(CN)6, used in making blue pigments, blueprint paper, and ferricyanide.
Century Dictionary and Cyclopedia
- n. A compound of a base or basic radical with ferrocyanogen. Potassium ferrocyanide, or yellow prussiate of potash, is commercially the most important ferrocyanide, being the starting-point for the production of all the cyanogen compounds. It is prepared by fusing in iron pots potassium carbonate, various sorts of animal refuse, as bone, hair, blood, etc., and iron-filings. The fused mass is digested with water, and the yellow prussiate of potash separated by crystallization. It is a powerful oxidizing agent, and is used in the arts.
