Iron oxide pigments remain a popular choice for many applications

Characteristics : Iron oxide pigments are a type of inorganic pigment that has been used for centuries to add color to a variety of materials. These pigments are made from iron oxide, which is a naturally occurring mineral that is found in rocks and soils. Iron oxide pigments are known for their excellent lightfastness, weather resistance, and chemical stability, which makes them ideal for use in a wide range of applications.The color is beautiful and durable, resistant to strong sunlight and climate change, as well as alkali resistance, mortar resistance, etc., and it has no impact on the properties of cement. It has strong tinting strength, has the most suitable particle size and particle structure, and has good dispersibility. 

Uses：Iron oxide pigments have been widely used in various industries due to their excellent properties such as high tinting strength, good dispersibility, and excellent lightfastness. These pigments are commonly used in the production of paints, coatings, plastics, ceramics, and construction materials.

In the paint and coating industry, iron oxide pigments are used as colorants to provide a wide range of colors, including red, yellow, brown, and black. These pigments are also used in the production of rust inhibitors, anti-corrosion coatings, and fire-retardant coatings.

Another growing application for iron oxide pigments is in the production of plastics. These pigments are used to add color to a variety of plastic products, including toys, packaging materials, and automotive parts. Iron oxide pigments are preferred over other types of pigments because they are resistant to fading and discoloration, even when exposed to sunlight and other environmental factors.

Iron oxide pigments are also used in the production of ceramics, where they are used to add color to a variety of ceramic products, including tiles, dishes, and decorative objects. Iron oxide pigments are preferred over other types of pigments because they are able to withstand high temperatures without losing their color or chemical stability.

In the construction industry, iron oxide pigments are used as colorants for concrete, asphalt, and other construction materials. These pigments are also used in the production of paving stones, roofing tiles, and bricks.

In addition to their use in traditional applications, iron oxide pigments are also being used in new and innovative ways. For example, researchers are exploring the use of iron oxide pigments in the production of solar cells, where they are used to absorb sunlight and convert it into electricity. Iron oxide pigments are also being used in the production of magnetic materials, where they are used to create magnetic nanoparticles that can be used in a variety of applications, including drug delivery and magnetic resonance imaging (MRI).

Iron oxide pigment used in making bricks：

The amount of iron oxide pigments in concrete products is limited to 1 ～10%.

To reduce the mechanical strength of the product, it is generally suitable to be 5-8%. At the same time, the iron oxide pigment does not contain the two compounds of lead and zinc oxide, which will affect the setting time and setting strength. Concrete products are sometimes required at 200. C and above are cured by hot pressing. Therefore, black and brown iron oxides that can be converted to iron red at 180 ° C must be heat stabilized first.

If used on terrazzo, the bottom layer is 2 to 3 cm thick and the surface layer is 15 cm thick.
