Physical properties
Colorless hexagonal or tetragonal crystals; density 4.7g/cm3; melts at 1188°C; insoluble in water; soluble in acids (reacts).
The Uses of Ferrous sulfide
Ferrous sulfide can be used as a laboratory source of H2S; in the ceramic industry; as a paint pigment; in anodes; in lubricant coatings.
The Uses of Ferrous sulfide
Iron(II) sulfide is used to generate hydrogen sulfide instantaneously by reacting with hydrochloric acid. In laboratory, Kipp?s apparatus is utilized for this purpose. It is used as a re-sulphurizing and alloying agent, as a reducing agent to remove heavy metal impurities from phosphoric acid. It is used to control hydrogen embrittlement in alloy and stainless steel industries.
What are the applications of Application
Iron(II) sulfide is a non-stoichiometric, inhomogeneous product
Flammability and Explosibility
Non flammable
