Ferric chloride is a kind of covalent compound. The brown one is anhydrous ferric chloride, and the orange one is ferric chloride containing six crystal water. Anhydrous ferric chloride is obtained by drying ferric chloride hexahydrate. Anhydrous ferric chloride has stronger oxidizability than hexahydrate ferric chloride.

Generally, ferric chloride is used as coagulant in industrial production. As a covalent compound, ferric chloride can enhance the strength and corrosion resistance of concrete, and can be used as mordant in printing and dyeing industry, catalyst and oxidant in industry. Due to the difference of production process, ferric trichloride generally has liquid ferric trichloride and solid ferric trichloride in the market. The price of different ferric trichloride varies greatly. When using, it is better to choose the appropriate ferric trichloride, and the cost performance is also higher.

If you want to know more about the price, quality and specific use of ferric chloride, you'd better consult the manufacturer, so as to have more guarantee.
