Alumina ceramic e bonolo ka lintho tse bonahalang, e holileng tsebong ea theknoloji ea tlhahiso, e batlang e le theko e tlase, e ntle ka thata ka thata le ho hanyetsa ho roala. E sebelisoa haholo liphaepheng tsa ceramic tse sa sebetseng, li-valve tse sa sebetseng joalo ka lisebelisoa tsa lesela, hape li ka tšeloa ka lithupa kapa tsa khomaretsoa leboteng le kahare la lisebelisoa tsa karohano joalo ka leloala le otlolohileng la indasteri, concentrator ea phofo le leholiotsoana, tse ka fanang ka 10 linako apara ho hanyetsa ea thepa bokaholimo. Ka thepa e sa sebetseng, karolo ea mmaraka ea lisebelisoa tsa alumina e ka fihla hoo e ka bang 60% ~ 70%.
Tšobotsi ea bohlokoa ka ho fetisisa ea thepa ea SiC ceramic ke ho hanyetsa mocheso oa mocheso. Tlas'a maemo a phahameng a mocheso, thepa e na le thepa e tsitsitseng ea mochine '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 deformation e nyenyane. E sebelisoa haholo indastering ea samente e fanyehiloeng ka preheater, nozzle ea ceramic e sa keneleng mocheso o phahameng, phala e oelang ka mashala le phala e fetisang mocheso o phahameng oa indasteri ea matla a futhumatsang. Ka mohlala, li-nozzles tsa li-burners limela tsa matla a mocheso li entsoe ka silicon carbide, 'me lihlahisoa li na le litšobotsi tsa ho hanyetsa mocheso o phahameng le ho hanyetsa ho apara. Mekhoa ea sintering ea silicon carbide ceramics e kenyelletsa ho etsa sintering le ho sesa ho se nang khatello. Litsenyehelo tsa ho etsa sintering li tlase, lihlahisoa li batla li le mahlahahlaha, 'me boleng ba lihlahisoa tsa vacuum sintering bo batla bo phahame. Boima ba lihlahisoa bo tšoana le ba lihlahisoa tsa alumina, empa theko ea eona e phahame haholo.
Ho hanyetsa ho kobeha ha lisebelisoa tsa ceramic tsa zirconia ho molemo ho feta tsa lisebelisoa tse brittle. Theko ea hona joale ea 'maraka ea phofo ea zirconia e batla e theko e boima, e sebelisoang haholo-holo libakeng tse phahameng, tse kang lisebelisoa tsa meno, lesapo la maiketsetso, lisebelisoa tsa bongaka, joalo-joalo.
