Graphite waa mid ka mid ah macdanta ugu jilicsan, allotrope ee kaarboonka aasaasiga ah, iyo macdanta crystalline ee walxaha carbonaceous. Qaab dhismeedkeeda crystalline waa qaab dhismeed lakabyo leh; masaafada u dhaxaysa lakabka mesh kasta waa 340 harag. m, kala dheeraynta atamka kaarboon ee lakabka isku midka ah waa 142 picometers, oo ka tirsan nidaamka crystals hexagonal, oo leh jajab dhamaystiran oo lakab ah, dusha sare ee jeexjeexa waxaa u sarreeya bonds molecular, soo jiidashada molecules waa daciif, sidaas awgeed dabeecadeeda dabiiciga ah Aad u wanaagsan; durugsan ee atamka kaarboon kasta waxa uu ku xidhan yahay saddex atamka carbon kale by bond bond si ay u sameeyaan molecule a covalent; Mar haddii atamka kaarboon kastaa uu soo saaro elektaroonig, elektaroonnadaas waxay u dhaqaaqi karaan si xor ah, sidaa darteed graphite waa kaari, Isticmaalka graphite waxaa ka mid ah soo saarista rasaasta qalinka iyo saliidaha, iyo kuwo kale.
Qalabka kiimikaad ee garaafka waa mid aad u xasiloon, sidaa darteed graphite waxa loo isticmaali karaa sida qalin qalin, midabka, walaxda dhalaalaysa iwm, erayada lagu qoray garaafka waxa lagu kaydin karaa wakhti dheer.
Graphite waxay leedahay sifooyinka iska caabinta heerkulka sare, sidaas darteed waxaa loo isticmaali karaa walxo celin. Tusaale ahaan, weelasha loo isticmaalo warshadaha birta waxay ka samaysan yihiin garaafka.
Graphite waxa loo isticmaali karaa walxo wax dhaqaajiya. Tusaale ahaan, ulaha kaarboon ee warshadaha korantada, electrodes togan ee aaladaha hadda jira ee meerkuriga, iyo burushyada dhamaantood waxay ka samaysan yihiin graphite.
