Used in steel production to enhance strength and hardness. Activated carbon serves in water and air purification by adsorbing contaminants. Graphite form is used in lubricants, batteries, and as electrodes in industrial processes. Carbon fibers provide lightweight, high-strength materials for aerospace, automotive, and sports equipment. Diamond form is utilized in cutting, drilling, and grinding tools due to extreme hardness. Also serves as a key component in organic chemistry and life-based compounds across biological systems.
