Thelesela la rabara la ceramic la alumina le sa tsofalengke thepa e kopaneng e sebelisoang haholo lefapheng la tšireletso ea ho roala indastering. E atolosa bophelo ba ts'ebeletso ea lisebelisoa maemong a thata ka ho kopanya khanyetso e phahameng ea ho roala ea alumina ceramic le thepa ea ho roala ea rabara. Liner ena e sebelisa alumina e le thepa ea mantlha e tala, ka ho eketsoa ha phofo ea ceramic le silicon oxide, e silang mochesong o phahameng hoo e ka bang 1700°C. Bongata ba alumina ea eona hangata ha bo ka tlase ho 95%, bongata bo fihla ho 3.5-3.9 g/cm³, 'me boima ba Rockwell bo holimo ho HRA85-90, ho netefatsa khanyetso e ntle ea ho roala. Litšebelisong tse sebetsang, liner ena e bonts'a sebopeho sa motsoako oa mekhahlelo e mengata: lera le ka holimo ke alumina ceramic, bohareng ke lera la rabara, 'me tlase ke poleiti ea tšepe e tšehetsang. Mealo ena e meraro e hokahane ka thata ka ts'ebetso ea vulcanization, e theha sistimi e kopaneng ea tšireletso ea ho roala.
Tshebetso e babatsehang ya moqomo ona o kopaneng e bonahala ka mahlakore a mangata: Ntlha ya pele, ho hanyetsa ha wona ho kgathala ho babatseha, ka thata ya alumina corundum ceramic e fihlang ka hodima HRA85, mme ho hanyetsa ho kgathala ho feta makgetlo a fetang 200 a tshepe e tlwaelehileng ya carbon. Ntlha ya bobedi, sehlahiswa se na le kgahlano e ntle le tshusumetso. Ka foromo e thata ya ceramic le moralo o ikgethang wa sedikadikwe, hammoho le lera la rabara, se ka hanela tshusumetso ya thepa e kgolo ka katleho. Ntlha ya boraro, moqomo o na le kgahlano e ntle le mocheso mme o ka sebetsa ka botsitso ka hara mocheso wa 0°C ho isa ho 250°C ka nako e telele. Ho feta moo, moqomo wa rabara o sebedisa foromo e ikgethang e nang le kgahlano le asiti le alkali, e kgonang ho mamella mafome dibakeng tse fokolang tsa asiti le alkaline. Mabapi le thepa ea 'mele, matla a ho hatella a liner ke ≥850 MPa, ho taboha ha KΙC ≥4.8 MPa·m1/2, matla a ho kopanya pakeng tsa rabara le ceramic (khatello ea ho beola) ≥3.0 MPa, 'me bophelo ba ho tsofala ha rabara ke ≥15, ho netefatsa botšepehi ba nako e telele ba sehlahisoa.
