I-Graphite ingenye yamaminerali athambile kakhulu, i-allotrope ye-elemental carbon, kanye ne-crystalline mineral yezinto ze-carbonaceous. Uhlaka lwayo lwe-crystalline luyisakhiwo esinezingqimba eziyisikwele; ibanga phakathi kwengqimba ngayinye ye-mesh liyizikhumba ezingu-340. m, isikhala sama-athomu e-carbon kungqimba olufanayo lwenethiwekhi singama-picometer angu-142, okungesistimu ye-crystal enezikwele eziyisikwele, enoqhekeko oluphelele olunezingqimba, ubuso boqhekeko bubuswa yizibopho zama-molecule, futhi ukukhanga kuma-molecule kubuthakathaka, ngakho-ke ukuntanta kwayo kwemvelo Kuhle kakhulu; umngcele we-athomu ngayinye ye-carbon uxhunywe kwamanye ama-athomu amathathu e-carbon ngokubopha kwe-covalent ukwakha i-molecule ye-covalent; njengoba i-athomu ngayinye ye-carbon ikhipha i-electron, lawo ma-electron angahamba ngokukhululeka, ngakho-ke i-graphite iyi-conductor, Ukusetshenziswa kwe-graphite kufaka phakathi ukukhiqizwa kwama-pencil leads kanye nama-lubricant, phakathi kokunye.
Izakhiwo zamakhemikhali ze-graphite zizinzile kakhulu, ngakho-ke i-graphite ingasetshenziswa njenge-pensela lead, i-pigment, i-polishing agent, njll., futhi amagama abhalwe nge-graphite angagcinwa isikhathi eside.
I-Graphite inezimpawu zokumelana nokushisa okuphezulu, ngakho-ke ingasetshenziswa njengento evimbela ukugqwala. Isibonelo, izitsha ezisetshenziswa embonini yensimbi zenziwe nge-graphite.
I-Graphite ingasetshenziswa njengento eqhuba ugesi. Isibonelo, izinduku zekhabhoni embonini kagesi, ama-electrode amahle amadivayisi wamanje we-mercury positive, kanye namabhulashi konke kwenziwa nge-graphite.
