Ferrous sulfide

CAS: 1317-37-9
Molecular Formula: FeS
Molecular Weight: 87.91
Product description:A compound formed by two element sulfur and iron, dark brown or black lump crystal or granule, chunks of metallic luster. Relative density 4.74, melting point is 1193 ~ 1199 ℃. Does not dissolve in ammonia, poorly soluble in water, soluble in dilute acid, let out poisonous hydrogen sulfide gas. In the moist air, gradually oxidized into ferroferric oxide and sulfur.It is mainly used for making hydrogen sulfide gas, used as analytical reagent. Industry to make ceramics and paint and paint. Also use it to other ferrous salt making. At high temperatures, ferrous sulfide can be oxygen or ozone oxidation iron oxide or sulfate; Can be carbon or manganese metal back into elemental iron. Ferrous sulfide dissolves in oxidizing acid generate trivalent iron and sulfur, sulfur dioxide, or sulfuric acid; In non oxidizing acids generated bivalent iron salt and hydrogen sulfide.
