Amashubhu e-alumina e-ceramic amelana nokuguguleka asikwa ngokulandelana kwezinyathelo zenqubo.
Okokuqala, izinto zokusetshenziswa zamapayipi e-alumina e-ceramic angagugi ikakhulukazi yi-Al2O3 yezimboni, elungiselelwe nge-bauxite (Al2O3▪3H2O) kanye ne-diaspore. Ku-Al2O3 enezidingo zokuhlanzeka okuphezulu, ngokuvamile ilungiswa ngezindlela zamakhemikhali. Ngesikhathi senqubo yokulungiselela, ithubhu le-alumina ceramic lengezwa ngezinto ze-ceramic ezihlanganisiwe njenge-zirconium oxide, i-silicon oxide, i-silicon nitride kanye nezinye izimpushana ngesikhathi se-calcination ukwandisa ubulukhuni namandla ayo.
Esigabeni sokusika, ukunqunywa kwamapayipi e-alumina ceramic kuncike kakhulu emishinini yokucubungula enembile kakhulu, njengemishini yokusika izintambo esheshayo noma imishini yokusika izintambo ehamba kancane. Imishini yokusika izintambo esheshayo ifanelekela ukucubungula amapayipi e-alumina ceramic anobubanzi obuncane nezidingo eziphezulu zobushelelezi bomphezulu; kuyilapho imishini yokusika izintambo ehamba kancane ifanelekela ukucubungula amapayipi e-alumina ceramic anobubanzi obukhulu nezidingo zobushelelezi bomphezulu ophansi. Ngesikhathi senqubo yokusika, kudingeka kugxilwe kakhulu ekhoneni lokusika kanye nesivinini sokusika ukuqinisekisa ubushelelezi nokunemba komphezulu wokusika.
Ngaphezu kwalokho, ukunqunywa kwamapayipi e-alumina ceramic kungabandakanya nezinqubo zokucubungula ezifana nokugaya nokujika. Inqubo yokugaya isebenzisa kakhulu umshini wokugaya. Ithuluzi lokugaya lingaba isondo lokugaya noma isondo lokugaya le-CBN. Kuyadingeka ukunaka ukuqina kokugaya nesikhathi sokugaya ukuqinisekisa ukushelela nokunemba kobuso bepayipi le-alumina ceramic. Inqubo yokuguqula isebenzisa kakhulu ama-lathe, kanti amathuluzi okuguqula angaba amathuluzi okuguqula insimbi ye-tungsten noma amathuluzi okuguqula i-carbide.
Ngokuvamile, ukusika nokwakhiwa kwamashubhu e-alumina e-ceramic angagugi kuyinqubo eyinkimbinkimbi edinga imishini yokucubungula enembile kakhulu kanye nokulawulwa kwenqubo enhle ukuqinisekisa ikhwalithi kanye nokusebenza komkhiqizo wokugcina.
