Alumina ceramic ke mofuta oa alumina (Al2O3) e le thepa e ka sehloohong ea ceramic, e sebelisoang potolohong e teteaneng ea filimi.Li-ceramics tsa alumina li na le conductivity e ntle, matla a mochine le ho hanyetsa mocheso o phahameng.
Li-ceramics tsa aluminium hajoale li arotsoe ka mefuta e 'meli: bohloeki bo phahameng le bo tloaelehileng.Bohloeki bo phahameng ba alumina ceramic bo feta 99.9% Al2O3 ea thepa ea ceramic, ka lebaka la mocheso oa eona oa sintering ho fihla ho 1650-1990 ℃, bolelele ba phetisetso ea 1 ~ 6μm, hangata e entsoe ka khalase e qhibilihisitsoeng ho nka sebaka sa crucible ea platinum.Ka lebaka la phetiso ea eona e bobebe le ho hanyetsa ho bola ha tšepe ea alkali, e ka sebelisoa joalo ka lebone la lebone la sodium, indastering ea lisebelisoa tsa elektroniki le eona e ka sebelisoa e le boto e kopaneng ea potoloho le lisebelisoa tse phahameng tsa maqhubu.
Li-ceramics tse tloaelehileng tsa alumina li arotsoe ka porcelain ea 99, porcelain e 95, porcelain e 90, porcelain e 85 le mefuta e meng ho latela litaba tsa Al2O3, ka linako tse ling litaba tsa Al2O3 ho 80% kapa 75% le tsona li nkuoa e le letoto le tloaelehileng la alumina ceramic.Har'a tsona, lisebelisoa tsa 99 tsa alumina ceramic li sebelisetsoa ho etsa mocheso o phahameng oa mocheso, li-tube tsa sebōpi le lisebelisoa tse khethehileng tse sa sebetseng, tse kang li-ceramic bearings, litiiso tsa ceramic le li-valve tsa metsi, joalo-joalo 95 alumina ceramic thepa e sebelisoa haholo-holo e le ho thibela kutu, ho se mamelle. likarolo;Lisebelisoa tsa 85 alumina ceramic hangata li kopantsoe le karolo ea talc, ho ntlafatsa thepa ea motlakase le matla a mochini, 'me li ka tiisetsoa ka molybdenum, niobium, tantalum le lisebelisoa tse ling, tse ling hape li sebelisoa e le lisebelisoa tsa vacuum tsa motlakase.
