Iron oxide powder is a common inorganic pigment composed of iron oxide particles. Iron oxide pigments can be divided into red, yellow, brown and black and other colors, and are widely used in construction, paint, cosmetics, plastics, rubber and other industries for coloring and dyeing. Because of its excellent corrosion resistance and light resistance, it is also widely used in metal anticorrosion, electronics, metallurgy and other fields.
