What is Blue Iron Oxide

Blue iron oxide, also known as iron oxide blue, is mainly composed of magnetite, which makes it highly magnetic. Its crystal belongs to isometric crystal system oxide mineral. The appearance is mostly dark blue or light blue powder, with bright color and high coloring power. Construction grade can be used for coloring paving stones, colored concrete blocks, split bricks, interlocking bricks, colored rigid bricks, roof tiles, rubber bezels, slurries, colored asphalt, permeable asphalt concrete, sports tracks, wood plastic flooring WPC...

Factors affecting the quality of blue iron oxide

The particle size determines the quality of iron oxide blue and also its stability.

Its color depends mainly on the presence of colored ions. The mixing of colors needs to be operated proportionally, and there are certain intrinsic connections between the pigments.

In the color mixing of blue iron oxide pigments, the principle of pigment mixing should be understood. The more types of mixed pigments used, the lower their brightness and purity, and the color tends to be dark gray.

What are the advantages of blue iron oxide pigments

High coloring power. The stronger the coloring power, the brighter the color.

High light resistance. It is generally believed that the more alkali metals in iron oxide blue pigment, the stronger its light resistance. However, when mixed with white pigments such as titanium dioxide, the light resistance will decrease.

Wide range of uses. In high temperature environment, less moisture, the color will be more vivid. In low temperature environment, more moisture, the color will be darker.

The hue of this pigment ranges from dark blue to bright blue, which is somewhat related to its composition. The more alkali metal content in blue iron oxide, the more FE(CN)6 atomic groups, and the less water it contains, the brighter its color will be. In addition to the chemical composition, the hue, coloring power, dispersibility and oil absorption of iron blue are closely related to its particle size.
