Products Description

Iron oxide is a widely used inorganic pigment, the main components of which are ferric oxide (Fe₂O₃) and ferric oxide (Fe₃O₄). It has high stability, excellent light and atmospheric resistance, and is non-toxic and environmentally friendly. Iron oxide is widely used in pigments, magnetic materials, catalysts, polishing agents, and iron smelting. Its reddish-brown powder form (Fe₂O₃) is often used for coloring paints, plastics, and rubber, while its black crystalline form (Fe₃O₄) is used in electronic materials due to its magnetism. Iron oxide is reasonably priced and cost-effective, making it an indispensable material in industrial production.
