Red Iron Oxide Applications

Glass Coloration

Red iron oxide serves as an effective glass colorant due to its high iron content (>95% Fe₂O₃). It is used to control the ultraviolet and infrared transmission of commercial glass production, creating amber coloration.

The material works well combined with anthracite or iron pyrite, avoiding unwanted sulfides that destabilise glass. The consistency and purity of our grades ensure repeatable colour results batch to batch.

Paints, Coatings & Construction

Red iron oxide pigments are relatively low-cost materials that resist colour change due to exposure to sunlight, with good chemical resistance. Primary uses include paints, coatings and construction materials such as:

• Concrete products
• Mortar and paving stones
• Roofing tiles
• Red oxide metal primers (prevent rust on ferrous metal surfaces)

Drilling Fluids

Hematite (red iron oxide mineral) functions as a weighting agent in oil and gas drilling operations. It contributes to an increased density in the fluid, helping to:

• Maintain hydrostatic pressure in the wellbore
• Carry drill cuttings to the surface
• Keep drill bits cool during operation
• Stabilise the wellbore and prevent blowouts

It is used in both Oil-Based Mud (OBM) and Water-Based Mud (WBM) systems.
