Mabapi le lirafshoa tsa Silicon Carbide le SiC

Silicon Carbide e na le khanyetso e ntle ea ho bola, matla a phahameng a mochini, ts'ebetso e phahameng ea mocheso, karolo e tlase haholo ea katoloso ea mocheso, le ho hanyetsa mocheso o betere ho feta lithemparetjha tse phahameng haholo tsa aluminium. Silicon carbide e entsoe ka tetrahedra ea carbon le liathomo tsa silicon tse nang le maqhama a matla ka har'a kristale lattice. Sena se hlahisa thepa e thata haholo le e matla. Silicon carbide ha e hlaseloe ke asiti leha e le efe kapa alkalis kapa letsoai le qhibilihisitsoeng ho fihla ho 800ºC. Moeeng, SiC e etsa lesela le sireletsang la silicon oxide ho 1200ºC mme e khona ho sebelisoa ho fihlela ho 1600ºC. Thermal conductivity e phahameng e kopantsoeng le katoloso e tlase ea mocheso le matla a phahameng li fa thepa ena litšobotsi tse ikhethang tsa ho hanyetsa mocheso oa mocheso. Li-ceramics tsa silicon carbide tse nang le litšila tse nyane kapa tse se nang moeli oa lijo-thollo li boloka matla a tsona ho fihlela mocheso o phahameng haholo, li atamela 1600ºC ntle le tahlehelo ea matla. Ho hloeka ha lik'hemik'hale, ho hanyetsa tlhaselo ea lik'hemik'hale ka mocheso, le ho boloka matla mochesong o phahameng ho entse hore thepa ena e ratoe haholo e le litšehetso tsa li-wafer tray le li-paddles ka har'a libopi tsa semiconductor. Thcell nameelectrical conduction ea thepa e lebisitse ho ts'ebeliso ea eona ea ho hanyetsa likarolo tsa mocheso bakeng sa libopi tsa motlakase, hape e le karolo ea bohlokoa ho li-thermistors (mocheso o fapaneng oa li-resistors) le ho li-varistors (voltage variable resistors). Lisebelisoa tse ling li kenyelletsa lifahleho tsa tiiso, lipoleiti tsa ho roala, li-bearings le li-liner tubes.
