Impuphu ye-graphite iyinto eguquguqukayo kakhulu ebaluleke kakhulu kuzo zonke izimboni ngenxa yezakhiwo zayo zamakhemikhali nezomzimba ezihlukile. Ukusetshenziswa kwayo kuqala kusukela ekugcotshweni nasekusetshenzisweni kwensimbi kuya ekugcinweni kwamandla kanye nokukhiqizwa okuthuthukisiwe. Impuphu ye-graphite esezingeni eliphezulu iqinisekisa ukusebenza kahle okuthuthukisiwe, ukuzinza, kanye nokuqina ezinqubweni zezimboni. Lesi sihloko sihlola izici ezibalulekile zempuphu ye-graphite esezingeni eliphezulu, ukusetshenziswa kwayo okuyinhloko kwezimboni, kanye neziqondiso zokukhetha ibanga elifanele izidingo ezithile.
UkuqondaUmgubo weGraphite
Incazelo kanye nezakhiwo
Impuphu ye-graphite iwuhlobo lwe-carbon oluyikristali, oluvela ngokwemvelo noma olukhiqizwa ngokwenziwa, olubonakala ngesakhiwo salo esinezingqimba zamashidi e-graphene. Ingqimba ngayinye iqukethe ama-athomu e-carbon ahlelwe ku-lattice enezinhlangothi eziyisithupha, enikeza izinto izakhiwo ezihlukile njengokushisa okuphezulu, ugesi, ukungangeni kwamakhemikhali, kanye nokugcotshwa.
