The released sulfate can lead to a secondary ettringite formation in the concrete matrix, but the degradation associated with this appears to be minor. The reaction of the iron sulfides was found to be very slow even when laboratory samples were exposed to elevated temperatures....
The basic structure of ammonium iron(III) sulfate consists of iron(III) ions coordinated with sulfate ions and ammonium ions. This compound is highly soluble in water. Safety Information: Ammonium iron(III) sulfate is not considered to be highly toxic. However, it may cause irritation to the...

Hybrid Steel-Polyethylene Fiber-Reinforced Iron Ore Tailing Concrete: Mechanical, Sulfate Freeze–Thaw Resistance, and Microscopic Characteristics This study examines the effects of iron ore tailing (IOT) replacement ratios and the hybridization of steel fiber (SF) and polyethylene (PE) fiber (PF) on...
Iron(II) sulfate is sold as ferrous sulfate, a soil amendment for lowering the pH of a high alkaline soil so that plants can access the soil's nutrients. In horticulture it is used for treating iron chlorosis. Ferrous sulfate can be used to sta...

Magnetic silica materials are widely applied in biomedical and environmental fields, but the current synthesis of low-cost, rapidly adsorbed magnetic silic
The mechanism of action involves the formation of insoluble iron hydroxide flocs, which can trap impurities and suspended particles in water, allowing them to settle and be removed. This helps in the purification and clarification of water. Dyeing and Printing: Iron(III) sulfate hydrate is also...
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 ...
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...
