I-conductivity ye-thermal kunye ne-conductivity yombane yeentonga ze-graphite ziphezulu kakhulu, kwaye umbane wabo uphezulu ngamaxesha angama-4 ngaphezu kwensimbi engenasici, amaxesha ama-2 aphezulu kune-carbon steel, kunye namaxesha angama-100 aphezulu kunezo zingezo zesinyithi ngokubanzi. I-conductivity yayo ye-thermal ayidluli nje isinyithi, isinyithi, i-lead kunye nezinye izinto zetsimbi, kodwa iyancipha ngokunyuka kweqondo lokushisa, elihluke kwizinto eziqhelekileyo zetsimbi. Kubushushu obuphezulu kakhulu, igraphite inokude ibe shushu. Ke ngoko, iipropathi zokufakelwa kwe-thermal zegraphite zithembeke kakhulu kumaqondo obushushu aphezulu.
Iintonga zegraphite zihlala zisetyenziselwa ukutsalwa kwe-electrothermal kwiziko lobushushu obuphezulu be-vacuum. Ubushushu bokusebenza obuphezulu bunokufikelela kwi-3000℃, kwaye kulula ukuba i-oxidized kumaqondo obushushu aphezulu. Ngaphandle kwe-vacuum, ingasetyenziselwa kuphela kwi-atmospheres engathathi hlangothi okanye yokunciphisa.
Ngenxa yeempawu zayo ezintle, igraphite isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo kwaye inokusetyenziswa njengento ephikisayo.
Iimveliso zegraphite zigcina iimpawu zokuqala zekhemikhali ze-flake graphite kwaye zineempawu eziqinileyo zokuzithambisa. I-graphite powder ibonakaliswe ngamandla aphezulu, ukuxhathisa kwe-asidi, ukuxhathisa kwe-corrosion, ukumelana nokushisa okuphezulu kunye nokuphantsi.
Igraphite inozinzo oluhle lweekhemikhali kwiqondo lobushushu begumbi kwaye ayigqwaliswanga yiyiphi na iasidi eyomeleleyo, isiseko esomeleleyo kunye ne-organic solvent, ngoko ke nokuba isetyenziswe ixesha elide, ukulahleka kweemveliso zegraphite kuncinci kakhulu, nje ukuba kucinywa. , iyafana nentsha.
