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.
Zinc oxide is white powder, with good hiding power and tinting power, widely used in printing & dyeing, rubber, coating, ceramics, feeds, cosmetics, pharmacy,ink, cable, electronics, phosphor, catalysts. 1. The product has small particle size, large specific surface area, strong adhesion and hiding power, which can greatly improve the efficacy of the coating. 2. The product has a small proportion and is not easy to form precipitation in the use or final product. 3. The product also has the function of shielding ultraviolet rays, and can play an anti-aging role in the coating.
Iron Oxide has various commercial uses such as iron ores, catalysts, pigments in dental composites; pigments in paints, coatings, colored concentrates. The magnetic properties of iron oxides have been exploited in a broad range of applications including magnetic seals and inks, magnetic recording media, catalysts, and ferrofluids. The steel and iron industries utilize iron oxide as a feedstock to mass produce iron, steel and other alloys.
