Iron sulfide concentrations and mineral associations triggering the internal deterioration of concrete structures are still enigmatic. Incidences of internal sulfate attacks induced by iron sulfide-containing concrete aggregates appear worldwide. Severe cases are reported from Canada, the United States of ...
“The anaerobic corrosion of iron structures is expensive to repair and can be a safety and environmental concern. It has been known for over 100 years that the presence of anaerobic respiratory microorganisms can accelerate iron corrosion. Multiple studies have suggested that there are sulfate red...
S70 is black iron/ steel powder used in fire works, concrete (to increase weight and create rust effects), soil additive, chemical reactions (production of iron sulfate, iron chloride, ..), electromagnetism (as iron filings). (Mesh 70) (Note: S70 is more coarse than S100) (S70 is being...
The iron sulfate can be iron(II) sulfate or iron(III) sulfate or a mixture thereof. Iron(II) sulfate can be used in the form of green salt or filter salt. The inventive iron sulfate is used in agriculture as fertilizer additive, moss control agent, pesticide and lawn fertilizer, in ...

Iron oxide black is produced via chemical synthesis using iron oxide yellow (FeO(OH)) or iron oxide red (Fe2O3) and/or iron(II) sulfate as starting chemicals which are converted/reacted in the presence of pure oxygen and caustic soda (precipitation process). ...

A research study investigating the impact of various anions on the rate of hematite leaching found that chloride ions were more effective in enhancing the reaction rate compared to sulfate ions. This phenomenon was attributed to the preferential adsorption of chloride ions on the reaction surface, ...
