1、 Overview:
Molecular formula: FeSO4 • 7h 2O, molecular weight: 278.05
Ferrous sulfate is monoclinic crystal of sky blue or green, with specific gravity of 1.898 and melting point of 64 ℃. It changes from heptahydrate to tetrahydrate at 56.6 ℃, monohydrate at 64 ℃ and anhydrous at 300 ℃. It decomposes when the temperature continues to rise. Soluble in water and corrosive. It absorbs moisture in humid air and is oxidized to rust color by air.
Production mode: the byproduct in the production of titanium dioxide from ilmenite.
2、 Quality standard: (GB 10531-2006)
