Graphite bụ otu n'ime mineral kachasị dị nro, allotrope nke elemental carbon, na mineral kristal nke ihe carbon. Usoro kristal ya bụ nhazi nwere akwa hexagonal; anya dị n'etiti oyi akwa mesh ọ bụla bụ akpụkpọ anụ 340. m, oghere nke atọm carbon n'otu oyi akwa netwọkụ ahụ bụ picometers 142, nke dị na sistemụ kristal hexagonal, yana nkewa zuru oke, elu nkewa ahụ na-achịkwa site na njikọ molekul, mmasị na molekul adịghịkwa ike, yabụ ike ya sitere n'okike dị mma nke ukwuu; a na-ejikọ mpụta nke atọm carbon ọ bụla na atọm carbon atọ ndị ọzọ site na njikọ covalent iji mepụta molekul covalent; ebe ọ bụ na atọm carbon ọ bụla na-ewepụta elektrọn, elektrọn ndị ahụ nwere ike ịkwaga n'enweghị nsogbu, yabụ graphite bụ onye na-eduzi, Ojiji nke graphite gụnyere imepụta ndu pensụl na mmanụ, n'etiti ndị ọzọ.
Njirimara kemịkalụ nke graphite siri ike nke ukwuu, yabụ enwere ike iji graphite mee ihe dị ka pensụl lead, pigmenti, ihe na-eme ka ihe dị ọcha, wdg, a pụkwara ịchekwa okwu ndị e ji graphite dee ruo ogologo oge.
Graphite nwere ihe ndị na-eguzogide okpomọkụ dị elu, ya mere enwere ike iji ya dị ka ihe na-anaghị eguzogide okpomọkụ. Dịka ọmụmaatụ, a na-eji graphite mee ihe ndị e ji eme ihe n'ụlọ ọrụ ígwè.
