Sebakeng sa theknoloji ea sebōpi se le seng sa kristale, ho sebetsa hantle le ho nepahala ha tsamaiso ea mocheso ke tsa bohlokoa. Ho fihlella ho ts'oana ha mocheso le botsitso ho bohlokoa ho holiseng likristale tse le 'ngoe tsa boleng bo holimo. Ho rarolla mathata ana,li-heaters tsa graphiteli hlahile e le tharollo e tsotehang, ka lebaka la conductivity ea bona e ikhethang ea mocheso. Sehloohong sena, re tla hlahloba bohlokoa ba li-heaters tsa graphite le karolo ea tsona tšimong ea mocheso oa libōpi tsa kristale tse le 'ngoe.
Graphite, mofuta oa carbon, o na le thepa e ikhethang e etsang hore e be thepa e loketseng bakeng sa lisebelisoa tse phahameng tsa mocheso. E 'ngoe ea thepa e joalo ke conductivity ea eona e tsotehang ea mocheso. Graphite e na le conductivity e phahameng haholo ea mocheso, e e lumellang ho fetisetsa mocheso ka potlako le ka mokhoa o nepahetseng ho pholletsa le sebopeho sa eona. Tšobotsi ena e ikhethang e etsa hore e be khetho e babatsehang bakeng salintho tse futhumatsangka liboping tsa kristale tse le 'ngoe.
The conductivity ea mocheso oa graphite e ka bakoa ke sebopeho sa eona se ikhethang sa kristale. Graphite e na le lihlopha tsa liathomo tsa carbon tse hlophisitsoeng ka lesela la hexagonal. Ka har'a karolo e 'ngoe le e' ngoe, liathomo tsa carbon li tlamahane ka thata, 'me li etsa maqhama a matla a covalent. Leha ho le joalo, tlamahano pakeng tsa lihlopha e fokola, e bakang mohaho o nang le li-electrone tse sa lefelloeng tse ka tsamaeang habonolo. Li-electrone tsena tse sa lefelloeng li kenya letsoho ho graphite e phahameng ea motlakase le ea mocheso.
Sebakeng sa mocheso oa libopi tsa kristale tse le 'ngoe,li-heaters tsa graphitee bapala karolo ea bohlokoa ho fumana mocheso o nepahetseng le o tšoanang. Ka ho tsamaisa mocheso ka katleho, ba thusa ho boloka mocheso o lakatsehang nakong eohle ea kholo ea kristale. Mocheso o babatsehang oa graphite o etsa bonnete ba hore mocheso o aroloa ka ho lekana ho pholletsa le sebaka sa mocheso, ho fokotsa likhahla tsa mocheso le libaka tse chesang. Ho tšoana hona ho bohlokoa bakeng sa kholo e laoloang le e tsitsitseng ea likristale tse le 'ngoe, tse amang boleng le thepa ea tsona ka kotloloho.
Ho feta moo, e phahameng mogote conductivity eali-heaters tsa graphitee lumella lipotoloho tse potlakileng tsa ho futhumatsa le ho pholisa, ho fokotsa nako ea ts'ebetso ka kholo ea kristale e le 'ngoe. Mocheso o sebetsang hantle o fanoang ke graphite o nolofalletsa sebōpi ho finyella mocheso o lakatsehang ka potlako, ho matlafatsa tlhahiso ea tlhahiso ea kristale. Ntle le moo, bokhoni ba ho pholile ka potlako kamora ts'ebetso ea kholo bo thusa ho ntšoa ha kristale ka potlako le ho fokotsa nako ea tlhahiso ka kakaretso.
Li-heaters tsa graphitee boetse e bontša botsitso bo botle ba mocheso, e ba nolofalletsang ho mamella mocheso o feteletseng oo ba kopanang le oona libakeng tsa sebōpi sa kristale se le seng. Li ka sebetsa ka mocheso o phahameng ntle le ho senyeha ho hoholo kapa ho khopama. Botsitso bona ba mocheso bo tiisa nako e telele le ho tšepahala ha li-heaters, ho fokotsa litlhoko tsa tlhokomelo le nako ea ho fokotseha ha mokhoa oa ho hōla ha kristale.
Molemo o mong oali-heaters tsa graphiteke ho lumellana ha tsona le maemo a sepakapaka kapa maemo a laoloang a atisang ho sebelisoa kholong e le 'ngoe ea kristale. Graphite ha e sebetse ka lik'hemik'hale 'me ha e sebetsane le likhase tse ngata, e e lumella ho boloka thepa ea eona ea mocheso libakeng tse fapaneng. Sena se versatility se etsali-heaters tsa graphitee loketse mefuta e mengata ea mekhoa ea ho holisa kristale, ho kenyeletsoa Czochralski, Bridgman, le mekhoa ea libaka tse phaphametseng.
Qetellong, e ikhethang mogote conductivity eali-heaters tsa graphitee etsa hore e be tsa bohlokoa haholo tšimong e futhumatsang ea libopi tsa kristale tse le 'ngoe. Bokhoni ba bona ba ho fetisetsa mocheso ka katleho le ho boloka ho tšoana ha mocheso ho bohlokoa bakeng sa kholo e laoloang ea likristale tse le 'ngoe tsa boleng bo holimo. Li-heaters tsa graphite li thusa ho futhumatsa le ho pholisa ka potlako, li ntlafatsa tlhahiso, 'me li fana ka botsitso bo botle ba mocheso libakeng tse feteletseng. Ha tlhoko ea likristale tse nang le ts'ebetso e phahameng e ntse e hola, bohlokoa ba lifuthumatsi tsa graphite ho nts'etsopele ea mahlale a kholo ea kristale bo ke ke ba fetisoa.
