Alumina ceramic e bonolo ka thepa, e holile theknolojing ea tlhahiso, e theko e tlase, e ntle ka ho thatafala le ho hanyetsa ho tsofala. E sebelisoa haholo-holo liphaepheng tsa ceramic tse sa tsofaleng, li-valve tse sa tsofaleng e le thepa ea lesela, 'me e ka boela ea kopanngoa ka li-studs kapa ea khomaretsoa leboteng le ka hare la lisebelisoa tsa karohano tse kang leloala la indasteri le otlolohileng, concentrator ea phofo le sefefo, tse ka fanang ka khanyetso ea ho tsofala ka makhetlo a 10 holim'a lisebelisoa. Linthong tse sa tsofaleng, karolo ea 'maraka ea thepa ea alumina e ka fihla ho hoo e ka bang 60% ~ 70%.
Tšobotsi ea bohlokoa ka ho fetisisa ea thepa ea ceramic ea SiC ke ho hanyetsa hantle mocheso. Tlas'a maemo a mocheso o phahameng, thepa ena e na le thepa e tsitsitseng ea mechini 'me e ka sebelisoa ka mokhoa o tsitsitseng ho 1800 ℃ nako e telele. Tšobotsi ea bobeli ke hore thepa ea silicon carbide e ka sebelisoa ho etsa lihlahisoa tse kholo tse nang le phetoho e nyane. E sebelisoa haholo indastering ea samente e leketlileng pele ho heater, nozzle ea ceramic e hanelang ho tsofala mochesong o phahameng, phaephe e oelang mashala le phaephe e fetisang mocheso o phahameng ea indasteri ea matla a mocheso. Mohlala, li-nozzle tsa li-burners lifemeng tsa motlakase oa mocheso li entsoe ka silicon carbide, 'me lihlahisoa li na le litšobotsi tsa ho hanyetsa mocheso o phahameng le ho hanyetsa ho tsofala. Mekhoa ea ho sila ea li-ceramic tsa silicon carbide e kenyelletsa ho sila ha karabelo le ho sila ntle le khatello. Litšenyehelo tsa ho sila ha karabelo li tlase, lihlahisoa li batla li le thata, 'me bongata ba lihlahisoa tsa ho sila ha vacuum tse se nang khatello bo phahame haholo. Bohloko ba lihlahisoa bo tšoana le ba lihlahisoa tsa alumina, empa theko ea tsona e phahame haholo.
Ho hanyetsa ho kobeha ha thepa ea letsopa ea zirconia ho betere ho feta ha thepa e robehang habonolo. Theko ea hona joale ea 'maraka ea phofo ea zirconia e theko e boima haholo, e sebelisoang haholo masimong a maemo a holimo, joalo ka thepa ea meno, masapo a maiketsetso, lisebelisoa tsa bongaka, jj.
