Introduction
1.Graphite fibers embedded in plastic material form high strength, lightweight composites 2.used in products such as tennis rackets, fishing rods, aircraft's and canoes. 3.Being good conductor, graphite is used for electrodes in batteries and industrial electrolysis. 4.Crucibles made from graphite are inert to dilute acids and alkalies. 5.Being highly porous, activated charcoal is used in adsorbing poisonous gases used in water filters to remove organic contaminators and in air-conditioning system to control odor. 6.Carbon black is used as black pigment in black ink and as filler in automobile tires. 7.Coke is used as a fuel and largely as a reducing agent in metallurgy. 8.Diamond is a precious stone and is used in jewelry.
