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, pencils, and as an electrode material in batteries and industrial electrolysis. Carbon black is added to tires and rubber products for durability and UV protection. As a refractory material, it withstands high temperatures in furnaces. Diamond form is utilized in cutting, drilling, and grinding tools due to extreme hardness. Emerging applications include carbon fibers in aerospace and automotive industries for lightweight structural components, and nanomaterials like graphene and carbon nanotubes in electronics and advanced composites.
