Detailed Product Description
Molecular Formula: FeSO4.7H2O
Appearance: Light blue green crystal
Properties: Glaucous crystallization. The relative density 1.897, melting point degree into four 64 when water and salt, salt water into degree when 65. In the wet air oxidation as alkali type sulphuric acid easy high iron into yellow. Soluble in water, insoluble in alcohol. Aqueous easy oxidation.
Usage: It is mainly used to make pigment such as Ferric Oxide series products (such as iron oxide red, Iron oxide black, Iron oxide yellow etc. ). It can also be directly used as the flocculant for waste water treatment, for purification of water, for producing ferric sulfate, for iron containing catalyst, or as additive in compound fertilizer, as well as for production of FeSO4. H2O.
