CAS 1309-37-1 Reddish-Brown Powder Iron(III) Oxide Pigment Fe2O3 Ferric Oxide

Ferric oxide, also known as iron(III) oxide or hematite, is a naturally occurring mineral compound with the chemical formula Fe2O3. It is one of the most common and stable forms of iron oxide.

Description:

• Chemical Formula: Fe2O3
• Molecular Weight: 159.69 g/mol
• Appearance: Ferric oxide is typically a reddish-brown to black powder. It can also occur naturally as red or brown crystals.

Technical Data:

• Density: The density of ferric oxide can vary depending on its specific form and particle size. It ranges from around 5.2 to 5.3 g/cm3.
• Melting Point: The melting point of ferric oxide is approximately 1,565°C.
• Solubility: Ferric oxide is insoluble in water and most organic solvents.
• Stability: It is chemically stable under normal conditions and does not decompose readily.

Features:

• Pigment: Ferric oxide is widely used as a pigment due to its vibrant colors, mainly red, brown, and black. It provides excellent color stability and resistance to fading, making it suitable for applications where long-lasting color is desired.
• UV Absorption: It exhibits UV absorption properties, which can make it useful in sunscreens and other UV-protective products.
• Non-Toxic: Ferric oxide is considered non-toxic and is widely used in various industries, including cosmetics, Chemical, and food.
• Heat Stability: It has good heat stability, making it suitable for applications that require resistance to high temperatures.
• Magnetic Properties: In some forms, such as magnetite (Fe3O4), ferric oxide exhibits magnetic properties and is used in magnetic recording media and as a magnetic pigment.

Applications:

• Pigments and Colorants: Ferric oxide is extensively used as a pigment in paints, coatings, ceramics, plastics, and inks. The red and brown shades are commonly used in the cosmetic industry for lipsticks, blushes, eyeshadows, and other makeup products.
• Construction Materials: It is used in the production of construction materials such as concrete, bricks, tiles, and paving stones to provide color and improve durability.
• Chemical: Ferric oxide can be used as a coloring agent in Chemical tablets, capsules, and other dosage forms.
• Polishing Agents: Fine particles of ferric oxide are used as a polishing agent in metal finishing and lens polishing.
• Magnetic Storage Media: In the form of magnetite (Fe3O4), ferric oxide is utilized in magnetic tapes, hard drives, and other magnetic storage media.
