Graphite block yog ib qho ntxhia ntuj tsim los ntawm cov pa roj carbon atoms teem rau hauv cov duab hexagonal honeycomb. Nws muaj cov khoom zoo ntawm lub cev xws li hluav taws xob conductivity, thermal conductivity, tsawg ntom thiab siab zog, nrog rau cov khoom zoo xws li tshuaj lom neeg stability thiab corrosion kuj. Nws yog dav siv hauv roj teeb electrodes, tshav kub exchangers, lubricants, coatings, catalyst carriers thiab electronics.
