Used in steel production to enhance strength and hardness. Activated carbon serves as an adsorbent in water purification and air filtration systems. 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 used in cutting, grinding, and drilling tools due to its hardness. Also serves as a key component in organic compounds and life molecules.
