Iron is widely used in the production of steel, which is essential for construction, automotive manufacturing, and infrastructure development due to its strength and durability. It serves as a key component in machinery, tools, and industrial equipment. In powdered form, iron is used in certain chemical reactions as a catalyst, especially in ammonia synthesis via the Haber process. Iron compounds are applied in water treatment to remove impurities and in the formulation of pigments for paints and coatings. Additionally, iron is a critical nutrient in pharmaceuticals and dietary supplements to treat iron-deficiency anemia. In agriculture, iron is added to fertilizers to support chlorophyll production and healthy plant growth.
