I-graphite ingenye yamaminerali athambile kakhulu, i-allotrope ye-elemental carbon, kanye ne-crystalline mineral of carbonaceous elements. Uhlaka lwayo oluyikristalu luyisakhiwo esinezingqimba eziyi-hexagonal; ibanga phakathi kwesendlalelo semeshi ngasinye yizikhumba ezingama-340. m, ukuhlukaniswa kwama-athomu e-carbon kungqimba olufanayo lwenethiwekhi ngama-picometers angu-142, okuyingxenye ye-crystal ye-hexagonal, ene-cleavage ephelele enezingqimba, i-cleavage surface ibuswa izibopho zamangqamuzana, futhi ukukhanga kwama-molecule kubuthakathaka, ngakho-ke ukuntanta kwayo kwemvelo Kakhulu. kuhle; i-periphery ye-athomu yekhabhoni ngayinye ixhunywe kwamanye ama-athomu ekhabhoni amathathu ngokuhlangana okuhlangene ukuze akhe i-molecule ehlangene; njengoba i-athomu ye-carbon ngayinye ikhipha i-electron, lawo ma-electron angakwazi ukuhamba ngokukhululekile, ngakho i-graphite ingumqhubi, Ukusetshenziswa kwe-graphite kuhlanganisa ukwakhiwa kwemithombe yepensela kanye nezinto zokugcoba, phakathi kokunye.
Amakhemikhali e-graphite azinzile kakhulu, ngakho i-graphite ingasetshenziswa njengomthofu wepensela, i-pigment, i-ejenti yokupholisha, njll., futhi amagama abhalwe nge-graphite angagcinwa isikhathi eside.
I-graphite inezici zokumelana nokushisa okuphezulu, ngakho-ke ingasetshenziswa njengento ephikisayo. Isibonelo, izinsimbi ezisetshenziswa embonini ye-metallurgical zenziwe nge-graphite.
I-graphite ingasetshenziswa njengento eqhubayo. Isibonelo, ama-carbon rods embonini kagesi, ama-electrode amahle wemishini yamanje ye-mercury positive, namabhulashi konke kwenziwa ngegraphite.
