Product Description

Ferric Oxide (Fe2O3), also known as Iron(III) Oxide or Red Iron Oxide, is a reddish-brown inorganic compound widely used in numerous industries due to its excellent chemical stability, non-toxicity, strong tinting strength, and low cost. With various grades available, including industrial, pigment, and food grades, Ferric Oxide serves as a multifunctional material across sectors such as pigments, construction, metallurgy, electronics, and environmental protection.

Physical and Chemical Properties

Ferric Oxide appears as a fine red-brown powder and exists naturally in the form of hematite. It is characterized by its high thermal stability, resistance to weathering, and chemical inertness in neutral and alkaline environments. It is insoluble in water and organic solvents but dissolves in strong acids such as hydrochloric or sulfuric acid.

• High Purity: Purity levels can reach 99% and above for high-end applications                     .

• Fine Particle Size: Particle size can be customized to suit applications requiring nano, sub-micron, or micron-grade materials.

• Color Fastness: Excellent resistance to light, heat, and alkali makes it a long-lasting pigment.

 

Applications

1. Pigment Industry

Iron oxide red pigment (CI 77491) is a popular choice in:

• Paints & Coatings: Used in water-based and solvent-based paints due to high opacity and strong tinting power.

• Construction Materials: Incorporated into cement, mortar, bricks, and ceramic tiles for long-lasting, UV-resistant color.

• Plastics & Rubber: Acts as a non-toxic colorant with excellent dispersibility.

• Printing Inks: Ensures vibrant coloration in packaging and label printing.

2. Polishing and Abrasives

Ferric Oxide, often referred to as "jeweler's rouge," is a classic polishing agent for:

• Optical lenses

• Metal components

• Precious stones

Its fine, hard particles deliver smooth and high-gloss finishes.

3. Metallurgy

Fe2O3 is a key raw material in:

• Iron and steel production

• Sintering and smelting processes

• Ferrite production for magnetic components

It contributes to improving magnetic properties and reducing environmental pollution compared to other iron sources.

4. Catalyst and Catalyst Support

Used in:

• A-m-monia decomposition

• Gas purification systems

• Hydrocarbon cracking

Its high surface area and stability at elevated temperatures make it ideal for catalytic conversions.

5. Battery & Electronics Industry

In advanced technology fields:

• Lithium-ion batteries: As an anode material, Fe2O3 offers high capacity and low cost.

• Sensors and semiconductors: Utilized for its semiconducting properties and high thermal stability.

• Photovoltaic devices: Plays a role in solar cell research due to favorable energy band characteristics.

6. Environmental Applications

As a sustainable material, Ferric Oxide is used in:

• Wastewater treatment: Removal of heavy metals and phosphates.

• Gas purification: Adsorption of h-y-drogen s-u-lfide (H2S) and other contaminants.

• Soil remediation: Acts as an immobilizing agent for heavy metals.
