Iron oxide refers to a group of chemical compounds consisting of iron and oxygen atoms, and it comes in various colors, including red, yellow, and black. These compounds are commonly used as pigments in a wide range of applications, from coloring paints, ceramics, and plastics to tinting cosmetics and food products. Red iron oxide (Fe2O3) is often used for its rich, rust-red hue, while yellow iron oxide (Fe2O3�·H2O) provides a vibrant yellow color. Black iron oxide (Fe3O4) is employed as a dark pigment in inks and coatings. Beyond their coloring properties, iron oxides are also used in magnetic materials, catalysts, and as a source of iron in nutritional supplements. The versatility of iron oxide pigments and their ability to add color and functionality to various products make them essential compounds in many industries.
