Silicone graphite ke thepa e kopantsoeng eo silicon carbide e khomaretsoeng ka holim'a karoloana ea graphite. E na le litšoaneleho tsa boima bo phahameng, matla a phahameng a mochine le ho hanyetsa ha silicon carbide, hammoho le thepa ea ho itlotsa le ho hanyetsa mocheso oa graphite. Ke thepa e loketseng ea likhohlano le thepa e tiisang mochini, e loketseng ho tiisa lipompo tse fapaneng tsa metsi, lipompo tsa oli, lipompo tsa lik'hemik'hale, le li-bearings tsa lipompo tse fapaneng tse lebelo le tse phahameng haholo. Ntle le moo, graphite e entsoeng ka siliconized e na le khanyetso e ntle ea oxidation, ho hanyetsa mocheso oa mocheso, porosity e tlase, le conductivity e itseng ea motlakase, 'me e ka sebelisoa e le lisebelisoa tse kang litšepe tse qhibilihisang tšepe le li-tubes tse ntseng li sebelisoa.
Sebopeho sa siliconized graphite se tšoana, bokaholimo bo lumellana le ka hare, 'me tekanyo ea sebopeho sa silicon carbide le graphite e ka fetoha. Ha litaba tsa silicon carbide li phahame, ho ba le letsoalo le leholo la thepa, matla a khatello a phahama, 'me resistivity e eketseha.
