Graphite, mofuta oa carbon, ke ntho e tsotehang e tsejoang ka thepa ea eona e ikhethang le mefuta e mengata ea lisebelisoa.Melamu ea graphite, haholo-holo, ba fumane tlhokomelo e kholo bakeng sa litšoaneleho tsa bona tse ikhethang le ho feto-fetoha ha maemo. Ka conductivity ea bona e ntle ea mocheso, conductivity ea motlakase, le matla a mochini,lithupa tsa graphiteli fetohile khetho e ratoang liindastering tse fapaneng. Sehloohong sena, re tla hlahloba litšobotsi tse hlahelletseng tsalithupa tsa graphitele lisebelisoa tsa bona tse fapaneng.
E 'ngoe ea melemo ea bohlokoa ealithupa tsa graphiteke eona e ikhethang ea mocheso oa mocheso. Graphite e bonts'a conductivity e phahameng ea mocheso ka lebaka la sebopeho sa eona se ikhethang sa athomo, se lumellang mocheso hore o fetele kapele ka thepa. Thepa ena e etsalithupa tsa graphitee sebetsa hantle haholo lits'ebetsong tse hlokang ho felisoa ha mocheso hantle, joalo ka li-exchangers tsa mocheso, libopi le litsamaiso tsa taolo ea mocheso. Ts'ebetso e phahameng ea mocheso oa lithupa tsa graphite e ba nolofalletsa ho aba mocheso ka mokhoa o ts'oanang, ho thibela libaka tse chesang tsa sebakeng seo le ho netefatsa ts'ebetso e nepahetseng lits'ebetsong tsa mocheso.
Melamu ea graphitehape li na le ts'ebetso e ntle ea motlakase, e li etsang hore e be tsa bohlokoa lits'ebetsong tsa motlakase le tsa elektroniki. Sebopeho se ikhethang sa athomo ea graphite se lumella ho tsamaea ka bolokolohi ha lielektrone, ho thusa ho phalla ha motlakase. Thepa ena e nolofalletsa lithupa tsa graphite ho tsamaisa motlakase hantle, e leng se etsang hore e be tse loketseng lits'ebetso tse joalo ka li-electrode, likhokahano tsa motlakase le likarolo tse tsamaisang motlakase. Motlakase o phahameng oa motlakase oa lithupa tsa graphite o tiisa ho hanyetsa ho fokolang le ho lahleheloa ke matla, ho tlatsetsa katlehong le ho tšepahala ha lisebelisoa tsa motlakase.
Ho phaella ho conductivity ea bona ea mocheso le ea motlakase, lithupa tsa graphite li bontša litšobotsi tse tsotehang tsa mechine. Li na le motsoako oa matla a phahameng le boima bo tlase, tse etsang hore li be bobebe empa li le matla. Lithupa tsa graphite li na le matla a makatsang, a li lumellang ho mamella meroalo e phahameng le khatello ea mochini. Matla ana a mochini a etsa hore lithupa tsa graphite li tšoanelehe bakeng sa lits'ebetso tsa meralo liindastering tse kang sefofane, likoloi le kaho. Li ka sebelisoa ka likarolo tse hlokang matla le bobebe, joalo ka likarolo tsa sefofane, lisebelisoa tsa lipapali, le lisebelisoa tse matlafatsang mehahong.
Ntho e 'ngoe e hlokomelehang ea lithupa tsa graphite ke ho hanyetsa ha tsona lik'hemik'hale. Graphite ha e na matla haholo 'me e bontša khanyetso e ntle ho mefuta e mengata e fapaneng ea li-acids, acid le solvents. Ho hanyetsa tlhaselo ea lik'hemik'hale ho etsa hore lithupa tsa graphite li tšoanelehe bakeng sa ho sebelisoa libakeng tse senyang, tse kang ho sebetsana le lik'hemik'hale, electroplating le ho hloekisa metsi a litšila. Ho tsitsa ha lik'hemik'hale tsa lithupa tsa graphite ho tiisa hore li phela nako e telele le ho tšepahala, esita le maemong a thata a lik'hemik'hale.
Li-graphite li boetse li fana ka thepa e ntle ea ho tlotsa ka lebaka la sebopeho sa tsona sa athomo. Matla a fokolang a li-interlayer a graphite a lumella lihlopha hore li thelle ka thelelo holim'a tse ling, ho fokotsa likhohlano le ho senyeha. Tšobotsi ena ea ho itlotsa e etsa hore lithupa tsa graphite e be khetho e ntle bakeng sa lits'ebetso tse kenyelletsang likarolo tse thellang kapa tse bilikang, joalo ka li-bearings, litiiso le likopano tsa mochini. Lintho tse tlotsang tsa lithupa tsa graphite li kenya letsoho ho fokotseng khohlano, nako e telele ea bophelo ba likaroloana, le ho ntlafatsa ts'ebetso ea ts'ebetso.
Qetellong, lithupa tsa graphite li na le thepa e ikhethang e li etsang hore li be molemo haholo lits'ebetsong tse fapaneng. Ts'ebeliso ea tsona e phahameng ea mocheso, motlakase oa motlakase, matla a mochini, ho hanyetsa lik'hemik'hale, le thepa ea ho tlotsa li kenya letsoho ts'ebelisong ea tsona e fapaneng liindastering tse kang taolo ea mocheso, lisebelisoa tsa elektroniki, kaho le ts'ebetso ea lik'hemik'hale. Ho feta moo, lithupa tsa graphite li fumana thuso lefapheng la bongaka ba liphoofolo, haholoholo kalafong ea meno ea equine. Ha liindasteri li ntse li tsoela pele ho batla lisebelisoa tse tsoetseng pele bakeng sa litlhoko tsa tsona tse fapaneng, lithupa tsa graphite li lula e le khetho e tšepahalang le ea bohlokoa, e fanang ka motsoako oa thepa e lakatsehang e ntlafatsang ts'ebetso, ho tšoarella, le katleho lits'ebetsong tse ngata.
