I-alumina ephezuluiibhola zokugaya ze-alumina ceramiczizixhobo zeseramikhi zobunjineli eziphambili ezenziwe ikakhulu yi-aluminium oxide (Al₂O₃), ngokuqhelekileyo zinomthamo ongaphezulu kwe-90%. Zibonisa ubulukhuni obuphezulu, ukumelana nokuguguleka okuphezulu, uzinzo oluhle kakhulu lweekhemikhali, kunye nongcoliseko oluphantsi, nto leyo eyenza ukuba zisetyenziswe kakhulu kwiinkqubo zokusila ezimanzi okanye ezomileyo kumashishini afana neeseramikhi, iipeyinti, iikhemikhali, imigodi, kunye nezixhobo ze-elektroniki. Ngobuninzi obuphezulu kwe-3.6 g/cm³ kunye nobunzima beVickers obufikelela kwi-HV1500 nangaphezulu, ziphucula kakhulu ukusebenza kakuhle kokusila ngelixa zinciphisa ukusetyenziswa kwemidiya.
Iingenelo zabo eziphambili zikwindlela ephucula kakhulu ukusebenza kakuhle kokusila kunye nokusebenza ngokwezoqoqosho. Ubunzima obuphezulu (ibanga lesi-9 lobunzima beMohs) buqinisekisa ukucolwa ngokukhawuleza kwezinto eziqinileyo; isakhiwo esincinci esifanayo sibonelela ngamanqanaba okuguguleka angaguqukiyo kwaye sandisa ubomi benkonzo. Ukungasebenzi kakuhle kweekhemikhali kuvumela ukumelana nee-asidi ezinamandla kunye ne-alkalis, kuthintela ungcoliseko lwezinto ezisemhlabeni. Intsalela yesinyithi ephantsi kakhulu (ngesiqhelo ingaphantsi kwe-0.01%) ibenza bafaneleke ngakumbi kwizicelo ezinobunono, ezifana nezixhobo zebhetri ye-lithium, iiglazes zodidi oluphezulu, kunye neeceramics ze-elektroniki.
Inkqubo yokuvelisa ibandakanya ukulungiswa komgubo olawulwa ngokuqinileyo, ukucinezelwa kwe-isostatic, kunye nokusila ngobushushu obuphezulu ukuze kufezekiswe uxinano oluphezulu, ukuqinisekisa ukuba imingxunya ephantsi kunye nokuqina okuphezulu kokuqhekeka. Ukuhlolwa komgangatho kubandakanya ukuchaneka kobukhulu, ububanzi, ubulukhuni, kunye nokumelana nempembelelo ukuhlangabezana neemfuno zezixhobo ezahlukeneyo zokusila kunye neemeko zenkqubo. Ukukhetha ngokufanelekileyo iinkcukacha (umz., ububanzi ukusuka kwi-1mm ukuya kwi-50mm) kunye nomlinganiselo wokuzalisa kunokuphucula ngakumbi ukucocwa kokusila kunye nokusebenza kakuhle kokusetyenziswa kwamandla.
Ngenxa yokwanda kweemfuno zobukhulu beesuntswana ezintle kunye nobunyulu obuphezulu ekuphuculweni kwemizi-mveliso, iibhola zokugaya ze-alumina ezine-alumina ephezulu ziye zaba zizixhobo zokugaya ezibalulekileyo kumacandelo anamhlanje eekhemikhali kunye nezinto ezintsha. Ngokuphucula umgangatho wemveliso kunye nokunciphisa iindleko zizonke, zibonelela ngesisombululo sobugcisa esithembekileyo kumashishini okucubungula ngokuchanekileyo. Kwixesha elizayo, ukwenziwa ngcono kwezinto kunye nokuqhubela phambili kubuchwepheshe bokuguqula umphezulu kuya kwandisa ngakumbi ububanzi besicelo sabo.
