Ferrous oxide

Ferrous oxide (CAS 1345-25-1 ), also known as Iron oxide (FeO), is an inorganic iron compound used as a precursor and functional material in metallurgical and industrial chemical processes.

It serves as a reactive iron source in applications where a divalent iron species is required, distinguishing it from the more oxidized ferric forms found in other industrial oxides.

In metallurgy and mining, it functions as a flux and intermediate in iron and steel production, where controlled oxygen activity in smelting operations is critical for efficiency.

Pulp and paper manufacturers use it in chemical recovery processes, particularly within kraft pulping systems where iron chemistry affects liquor composition and equipment performance.

Water treatment operations employ it as a precursor in the synthesis of iron-based coagulants and reactive media for contaminant removal in large scale municipal systems.

It also serves as a pigment intermediate and raw material in the production of mixed iron oxide colorants for ceramics and specialty coatings used in the construction industry.

Ferrous oxide is supplied as a black powder, with particle size and purity varying by application grade. Technical-grade material is the standard commercial form for most uses.

Purity levels are typically specified by iron content. Bulk quantities are available for industrial supply chains, with packaging options suited to moisture-sensitive handling requirements.
