Used as a pigment in paints, coatings, and construction materials due to its stable red-brown color and resistance to UV light.

Employed in water treatment processes to remove arsenic, phosphates, and other contaminants through adsorption and co-precipitation.

Acts as a precursor in the synthesis of iron-based materials and catalysts.

Utilized in pharmaceuticals and dietary supplements as a source of iron, particularly in the form of colloidal dispersions.

Found in some battery materials, especially in lithium-ion and iron-air battery systems, where it contributes to electrochemical performance.

Applied in environmental remediation to immobilize heavy metals in soil and groundwater.

Used in corrosion protection products for iron and metals, as it can form a protective film on metal surfaces against moisture and oxygen.
