I-alumina ephezuluamabhola okugaya e-alumina ceramicziyizinto zobumba zobunjiniyela obuthuthukisiwe ezakhiwe kakhulu nge-aluminium oxide (Al₂O₃), ngokuvamile ezinokuqukethwe okungaphezu kuka-90%. Zibonisa ubulukhuni obuphezulu, ukumelana nokuguguleka okuphezulu, ukuqina kwamakhemikhali okuhle kakhulu, kanye nokungcola okuphansi, okwenza zisetshenziswe kabanzi ezinqubweni zokugaya ezimanzi noma ezomile ezimbonini ezifana ne-ceramics, upende, amakhemikhali, izimayini, kanye nezinto ze-elekthronikhi. Njengoba ubukhulu ngokuvamile bungaphezu kuka-3.6 g/cm³ kanye nobunzima be-Vickers obufika ku-HV1500 noma ngaphezulu, zithuthukisa kakhulu ukusebenza kahle kokugaya ngenkathi zinciphisa ukusetshenziswa kwemidiya.
Izinzuzo zabo eziyinhloko zisekuthuthukiseni kakhulu ukusebenza kahle kokugaya kanye nokusebenza kwezomnotho. Ukuqina okuphezulu (ibanga lesi-9 lokuqina kwe-Mohs) kuqinisekisa ukugaywa okusheshayo kwezinto eziqinile; isakhiwo esincane esifanayo sinikeza amazinga okuguguleka ahambisanayo futhi sandisa impilo yesevisi. Ukungasebenzi kahle kwamakhemikhali kuvumela ukumelana nama-asidi aqinile nama-alkali, kuvimbela ukungcoliswa kwezinto ezingaphansi komhlaba. Izinsalela zensimbi eziphansi kakhulu (ngokuvamile ngaphansi kuka-0.01%) zizenza zifaneleke kakhulu ekusetshenzisweni okubucayi ubumsulwa, njengezinto zebhethri le-lithium, ama-glaze aphezulu, kanye ne-ceramics kagesi.
Inqubo yokukhiqiza ihilela ukulungiswa kwempuphu okulawulwa ngokuqinile, ukucindezela kwe-isostatic, kanye nokushiswa kwezinga lokushisa eliphezulu ukuze kufezwe ukuminyana okuphezulu, kuqinisekiswe ukuthi i-porosity iphansi kanye nokuqina kokuqhekeka okuphezulu. Ukuhlolwa kwekhwalithi kuhlanganisa ukunemba kobukhulu, ububanzi, ubulukhuni, kanye nokumelana nomthelela ukuze kuhlangatshezwane nezidingo zemishini yokugaya ehlukahlukene kanye nezimo zenqubo. Ukukhetha kahle imininingwane (isb., ububanzi obusukela ku-1mm kuya ku-50mm) kanye nezilinganiso zokugcwalisa kungenza ngcono kakhulu ukugaya kanye nokusebenza kahle kokusetshenziswa kwamandla.
Njengoba izidingo zobukhulu bezinhlayiya ezincane kanye nobumsulwa obuphezulu ekuthuthukisweni kwezimboni, amabhola okugaya e-alumina ceramic ane-alumina ephezulu abe yimithombo yokugaya ebalulekile emikhakheni yamakhemikhali yesimanje kanye nezinto ezintsha. Ngokuthuthukisa ikhwalithi yomkhiqizo kanye nokunciphisa izindleko eziphelele, ahlinzeka ngesisombululo sobuchwepheshe esithembekile sezimboni zokucubungula ngokunemba. Esikhathini esizayo, ukwenza ngcono ukwakheka kwezinto kanye nokuthuthuka kobuchwepheshe bokuguqulwa kwendawo kuzokwandisa kakhulu ububanzi bokusetshenziswa kwazo.
