Iron Sulfide an overview ScienceDirect Topics

For iron sulfide formation, although the chemical reactions describing sulfide chemistry are well known [7], the pathways for iron sulfide layer formation are still debated [11–13].The latest developments in the mechanism of FeS (mackinawite) formation involve a rapid formation of a thin layer by “direct” reaction, where the Fe atom does not leave the metal microstructure and reacts

The formation of iron sulphide on oxidised pyrite during

Oct 01, 2020· The increase in current density evidently shows that a higher amount of iron sulphide species was formed on the oxidised pyrite surface, while the positive shift of the peak indicates that the iron sulphide species formed during sulphidisation at- 400 mV and −500 mV became more resistant to oxidation than those at −300 mV.

The formation of pyrophoric iron sulphide from rust

Aug 01, 1987· Hydrogen sulphide present in crude oil can react with rust in the cargo tanks of oil tankers to give iron sulphide. The particular form of the sulphide produced depends on the temperature, the availability of hydrogen sulphide and the time of the reaction. Maijs [7] investigated the mineralogenetic aspects of the formation of iron corrosion

Formation of iron oxide and iron sulfide at high

May 01, 2018· 2. Iron sulfide formation and transformation at high temperature. The observed transformation sequence for iron sulfides under these conditions was mackinawite (1 day) → troilite (4 days) → pyrrhotite (7 days) → pyrite (12%)/pyrrhotite (21 days). The thickness of iron sulfide layer increased with time. 3.

Iron(II) sulfide Wikipedia

Biology and biogeochemistry. Iron sulfides occur widely in nature in the form of iron–sulfur proteins.. As organic matter decays under low-oxygen (or hypoxic) conditions such as in swamps or dead zones of lakes and oceans, sulfate-reducing bacteria reduce various sulfates present in the water, producing hydrogen sulfide.Some of the hydrogen sulfide will react with metal ions in the water or

How to prevent the spontaneous combustion of iron sulfide

When these sulfur compounds on the vessel wall of iron and iron oxide long-term corrosion, will generate iron sulfide (Fe2Ss). Iron sulfide, a dark brown or black mass with metallic luster, can spontaneously ignite when exposed to oxygen in the air. It is easier to ignite when exposed to air. The ignition point of the iron sulfide is about 40.

Sulfide To Sulfate Reaction Mechanism

Iron sulfide exists in coal formations in two structural states — pyrite and marcasite. Various authorities differ on which is the most common of the two types. Inasmuch as the oxidation rate is strongly dependent upon the structural state of the sulfide, the determination of the -abundances of the two modifications was undertaken first.
