Iron Oxide Black is a black powder at room temperature. As an inorganic compound, it exhibits stable chemical properties. Its core characteristics include strong alkali resistance, slow oxidation in air, and a certain degree of magnetism. Based on its excellent tinting strength, hiding power, lightfastness, weather resistance, and low toxicity, its primary application is as an important black inorganic pigment. It is widely used in coatings (including anti-rust paints and architectural coatings), inks, plastics, construction materials (such as colored cement and floor tiles), magnetic materials, as well as in fine chemicals and the electronics industry, among other fields.
