Used in steel production to enhance strength and hardness. Activated carbon serves in water and air purification due to its high adsorption capacity. Graphite form is used in lubricants, pencils, and as an electrode material in batteries and industrial electrolysis. Carbon fibers provide lightweight, high-strength materials for aerospace, automotive, and sports equipment. Diamond form is utilized in cutting, drilling, and grinding tools, as well as in high-performance electronics. Carbon black is added to tires and rubber products to improve durability and UV resistance. Also used in the production of carbon-based nanomaterials like graphene and nanotubes for advanced electronics and composites.
