Hematite

Hematite (CAS 1317-60-8) is a naturally occurring iron oxide mineral; also known as oligiste in certain European markets.

Where is Hematite used?

• Construction and industrial coatings: red-brown inorganic pigment and corrosion-inhibiting agent
• Protective coatings and primers: passive corrosion inhibition in heavy-duty industrial and marine paint systems
• Concrete and cement products: durable red-to-brown coloration that resists UV degradation and weathering
• Pulp and paper: filler and colorant where inorganic mineral stability is required
• Mining and metallurgy: dense medium in gravity separation processes
• It also serves as a primary iron ore feedstock for smelting.

Good to know: Synthetic iron oxide variants are available where tighter color consistency and purity are required.

Commercial specifications

• Fine powder; particle size and surface area specifications vary by application grade
• Iron oxide content typically specified by buyers for pigment and metallurgical use
