There are two kinds of ferric trichloride in the market: liquid and solid. The liquid ferric trichloride is generally brown liquid, while the solid ferric trichloride is generally black or yellowish brown powder or granular, because the liquid ferric trichloride is more troublesome in transportation and preservation. In addition, ferric trichloride is also dangerous goods, and the liquid ferric trichloride is more prone to accidents, At present, solid ferric chloride is mostly used in the market.
The solid ferric chloride can be divided into anhydrous ferric chloride and hexahydrate ferric chloride. From a chemical point of view, it does not belong to the same substance, but there is not much difference in the use effect. The difference between anhydrous ferric chloride and hexahydrate ferric chloride only lies in its physical and chemical properties.
Anhydrous ferric chloride has strong water absorption and is easily soluble in water. The dissolved ferric chloride solution is acidic and corrosive. Ferric chloride hexahydrate also deliquescence, soluble in water, the aqueous solution is acidic, generally speaking, most of the time we think it is the same product because of the same effect.
In terms of use, no matter what type of ferric chloride is, it can be used for water treatment, circuit board and metal etching, chlorination agent in metallurgy, dyeing agent in dyestuff industry, etc. the strong oxidation of ferric chloride is used as oxidant in many industries. The price of ferric chloride is cheap, and it is often used as the raw material of other iron salts in some industrial production.
