Used as a pigment in coatings, paints, and construction materials due to its stable black color and UV resistance.

Commonly found in anti-corrosion primers for steel structures because it forms a protective layer that inhibits rust.

Employed in the production of magnetic storage media and electronic components for its ferromagnetic properties.

Utilized in polishing compounds, especially for glass and metals, where it acts as a mild abrasive.

Applied in medical formulations, such as superparamagnetic iron oxide nanoparticles as contrast agents in MRI imaging, to enhance image clarity.

Found in thermite mixtures for welding and metal cutting due to its role as an oxidizer in high-temperature reactions.

Used in steel production to control iron composition in furnaces and in cosmetics like foundations and mascaras for intense, moisture-resistant black pigmentation.
