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.

Where is Ferrous oxide used?

• Metallurgy and mining: flux and intermediate in iron and steel production
• Pulp and paper: chemical recovery in kraft pulping systems
• Water treatment: precursor for iron-based coagulants and reactive media
• Ceramics and specialty coatings: pigment intermediate and raw material for mixed iron oxide colorants
• It serves as a reactive iron source where a divalent iron species is required.

Good to know: Distinguished from the more oxidized ferric forms found in other industrial oxides.

Commercial specifications

• Particle size and purity vary by application grade
• Purity levels typically specified by iron content
• Bulk quantities available, with packaging suited to moisture-sensitive handling
