1317-60-8 | Hematite (α-Fe₂O₃)

Chemical type

• Iron oxide

^[1]

• Iron oxide mineral
• Metal oxide (iron ore)

^[2]

Key properties

• High purity (phase-pure)
• Thermally stable
• Irregular, porous morphology

^[1]

• Main component: Fe₂O₃ (~96.7% in the sample)
• High density (~5.02 g/cm³)
• Surface hydroxyl groups (Fe–OH) that undergo protonation/deprotonation depending on pH
• Surface charge strongly depends on pH (isoelectric point ~pH 3–6)
• Can form coordination bonds with carboxyl groups from polymers (Fe–OOC interactions)

^[2]

• Red pigment in anti-corrosion coatings
• Cosmetic formulations
• Lithium iron phosphate (LFP) battery cathodes
• Ceramic magnetic materials
• Catalysts

^[1]

• Main mineral particle studied for flocculation behavior
• Target material in solid–liquid separation in mineral processing
• Iron ore feedstock for steel production

^[2]

Classification by use

• Pigments and colorants
• Battery materials
• Ceramic and magnetic materials
