Iron Oxides – Micaceous, Red, and Yellow Iron Oxide for Industrial Applications

Iron Oxides are chemically stable, high-performance minerals used for their coloring, anti-corrosion, heat resistance, and strengthening properties. Available in Micaceous Iron Oxide (MIO), Red Iron Oxide (Fe₂O₃), and Yellow Iron Oxide (FeO(OH)), they play a crucial role in paints, coatings, welding electrodes, foundries, and automotive friction materials.

At Ashok Minerals, we supply high-purity Iron Oxides in various grades, ensuring superior durability, consistency, and high efficiency in industrial applications.

Chemical Properties of Iron Oxides

1. Micaceous Iron Oxide (MIO)

• Chemical Formula: Fe₂O₃
• Physical Properties:
  • Lamellar (Flake-like) Structure: The unique flake-like arrangement gives MIO its excellent barrier properties, making it a highly effective material for coatings.
  • Excellent Corrosion Resistance: MIO is widely used as a protective coating due to its ability to resist rust and corrosion in industrial environments.
  • High Temperature and UV Stability: It performs well in high-temperature applications and is resistant to degradation from UV exposure, making it ideal for outdoor coatings and marine environments.

2. Red Iron Oxide

• Chemical Formula: Fe₂O₃
• Physical Properties:
  • High Tinting Strength and Opacity: Red Iron Oxide is a popular pigment due to its strong color and opacity, often used in paints and coatings.
  • Excellent Weather and Chemical Resistance: This form of Iron Oxide holds up well to exposure to weathering and chemicals, making it durable for outdoor and industrial use.
  • Thermal Stability up to 1000°C: It maintains its properties even at high temperatures, making it suitable for use in ceramics, pottery, and industrial coatings.

3. Yellow Iron Oxide

• Chemical Formula: FeO(OH)
• Physical Properties:
  • Converts to Red Iron Oxide When Heated: Yellow Iron Oxide undergoes a transformation at elevated temperatures, converting to red oxide, which is widely used as a pigment in the construction and art industries.
  • Good UV and Moisture Resistance: Its stable chemical composition allows it to resist UV degradation and moisture absorption, making it suitable for outdoor applications and coatings.
  • Fine Particle Size for Easy Dispersion: Yellow Iron Oxide’s fine particle size enhances its ability to mix smoothly in paints, coatings, and other applications.

Interesting Facts About Iron Oxides:

1. Used in Artistic Pigments: Iron oxides, especially red and yellow varieties, are commonly used as pigments in art and architecture. These natural pigments, often referred to as "ochre," have been used since ancient times to create cave paintings and murals.
2. Vital for Rust Formation: Iron oxide is the primary substance responsible for the formation of rust. When iron reacts with oxygen and moisture in the air, it forms iron oxide, which gives rust its characteristic reddish-brown color.
