iron disulfide

Iron disulfide is used in both steelmaking and casting. It is a good sulfur enhancer. Different areas of Iron disulfide use and play different roles. Therefore, it is clear when Iron disulfide is actually used. Don't get it wrong, otherwise it may affect the quality of the process.

Iron sulfide is a general term for compounds of iron and sulfur, mainly including ferrous disulfide, ferrous sulfide, and ferrous sulfide. Ventilation and dust management must be strengthened during the underground mining of pyrite, and the concentration of harmful ferroalloy gas such as SO2, CO, H2S in the mining site must be grasped at any time, and the pyrite lumps of spontaneous combustion of ore should be noticed.

Ferrous disulfide (FeS2) is a yellow crystal, which is the main component of pyrite and has diamagnetic properties. Pyrite has a melting point of 1171 ° C, a density of 5.0 g / cm3, and a cubic lattice; it is an inactive substance at room temperature. It becomes active when the temperature rises, and is heated in the air to oxidize to ferric oxide (see Iron oxide) ) And sulfur dioxide; heated to above 600 ° C in a vacuum to obtain sulfur. Iron disulfide can be used in the sulfuric acid industry.

Ferrous sulfide (FeS) is a brown-black mass; melting point is 1193 ～ 1199 ℃, density is 4.74 g / cm3; it is insoluble in water and soluble in aqueous acid solution, and produces hydrogen sulfide; it is easy to be oxidized by heating in air, and under vacuum Medium is heated to above 1100 ° C to obtain sulfur. Ferrous sulfide can be prepared by the direct reaction of two elements, or it can be obtained by the action of an aqueous ferrous salt solution and an alkali metal sulfide. It can be used to generate hydrogen sulfide gas in the laboratory; it can also be used in the ceramic and paint industry.

Ferrous trisulfide Fe2S3 is a yellow-green solid; relative density 4.3; decomposes under strong heat; insoluble in water, decomposes into ferrous sulfide and sulfur in hot water; decomposes on acid and releases hydrogen sulfide gas
