Iron oxide pigments remain stable at high temperatures and are therefore often used in products that are resistant to high temperatures, such as ceramics or refractory materials.

Compared to some other pigments, iron oxide pigments are often considered an environmentally friendly choice as they contain no heavy metals or other harmful substances.

Iron oxide pigments are widely adopted for their stability, weather resistance and versatility, and their relatively low cost makes them a cost-effective choice for making a wide range of color products.

Iron oxide pigments have excellent weathering resistance, with high resistance to light, chemicals and climate change, and are not easily faded or discolored.

Iron oxide pigments are extremely light stable and can therefore be exposed to outdoor environments for long periods of time without noticeable color fading.

Iron oxide pigments have excellent covering ability, which can effectively hide the color or imperfections of the underlying layer when covering the surface.

Iron oxide pigments are mainly composed of iron and oxygen elements. Depending on the oxidation state, they can be formed into a variety of colors, such as red, yellow, brown and black.

Iron oxide pigments maintain color stability during the preparation process and do not change color when exposed to heat or light.

Because iron oxide pigments are available in a variety of oxidation states, a wide range of colors can be achieved through different formulations and treatments, from bright to deep.

Iron oxide pigments are widely used in coatings, paints, plastics, rubber, ceramics, asphalt, cement and other fields to provide color stability and uniform tinting effect.

What is iron oxide?

Iron oxide is a compound produced by a chemical reaction between iron and oxygen, and is an important substance widely found in nature.

Iron oxides are known to have different compositions, such as iron(II) oxide (FeO) and iron(III) oxide (Fe 2 O 3), depending on the oxidation number. Both are iron oxides and are components of rust along with iron hydroxide.

Uses of Iron Oxide

Iron oxide is used in various fields due to its nature and properties.

1.Iron
Iron oxide is mainly mined in the form of Hematite and Magnetite. These iron oxides can be reduced at high temperatures to metallic iron, which is an essential material for the construction industry.

2. Magnetic materials
Some iron oxides are magnetic and are used as magnetic materials in compasses, loudspeakers, electric motors and recording media such as magnetic tapes and disks.

3.Pigment
Iron oxides are available in red, black and yellow colors and are used as pigments and dyes in painting, printing and dyeing applications.

4. Cosmetics and pharmaceuticals
It is used in medicines for anemia and in cosmetics such as lipstick and blush.

5. Healthcare
In the medical field, it is used as a contrast agent for MRIs.

Properties of Iron Oxide

Iron oxide has a variety of properties, some of the characteristic properties are listed below:

1. Color
Iron oxide compounds produce substances of different colors, including red, yellow, and black, making them valuable as pigments.

2. Magnetism
Magnetic iron oxides have strong magnetic properties, which are important for electrons and magnets.

3.Chemical Stability
Iron oxide is chemically stable and relatively resistant to acids and alkalis, making it suitable for use in a variety of environments.
