Iibhola zokugaya ze-alumina ze-ceramic ezingama-92%Zenziwe kakhulu ngomgubo we-alumina, zongezwa yi-metal oxides encinci, zize zenziwe ngokushisa okuphezulu. Ziyimilo engqukuva kwaye ziza ngobukhulu obahlukeneyo, kunye nobubanzi obuqhelekileyo obuqala kwi-0.5 mm ukuya kwi-10 cm. Le mveliso inobunzima obuphezulu, ukumelana nokuguguleka okugqwesileyo, ukumelana nokugqwala kweekhemikhali okuphezulu, kunye namandla aphakathi oomatshini. Uxinano lwayo luhlala luphakathi kwe-3.6 kunye ne-3.7 g/cm³, kwaye ubunzima bayo be-Mohs bunokufikelela kwi-9. Ngenxa yesakhiwo sayo esizinzileyo sekristale, igcina izinga eliphantsi lokukhuhla ngexesha leenkqubo zokusila ixesha elide, ithintela ungcoliseko lwezinto zomhlaba.
Iibhola zokugaya ze-alumina ceramic zisetyenziswa kakhulu kwiinkqubo zokugaya iibhola kumashishini afana neengubo, izixhobo zokwakha, iikhemikhali, kunye neeceramic. Ngexesha lokulungiselela iiglaze ze-ceramic, zinokunciphisa ngempumelelo ubungakanani beesuntswana zezinto kwaye zithintele ungcoliseko lwesinyithi; kushishino lwesamente, zisetyenziselwa ukugaya i-slag kunye ne-clinker; ekuvelisweni kweeceramics ze-elektroniki kunye nezixhobo zemagnethi, ubunyulu bazo obuphezulu kunye nokuzinza kuqinisekisa umgangatho wezixhobo zomgubo ophantsi. Ngaphezu koko, ekugayweni okumanzi kweedayi, ii-pigment, kunye nee-electrode ezilungileyo nezingalunganga zeebhetri ze-lithium, kuba iibhola zokugaya ze-alumina ceramic zinokumelana okuhle kwe-asidi kunye ne-alkali, zinokuba yindawo ephambili yokugaya.
Ukukhetha iibhola zokugaya ze-alumina ze-ceramic ezikumgangatho ophezulu ezingama-92% kufuna ukuqwalaselwa ngokupheleleyo kwezalathisi ezininzi zobugcisa. Okokuqala, umxholo wokwenyani we-alumina kunye nobuninzi bomthamo kufuneka kuvavanywe ukuqinisekisa ukuba ziyahlangabezana nomgangatho wokwakheka we-92% kunye noluhlu loxinano lwethiyori. Okwesibini, ukumelana nokuguguleka kufuneka kuhlolwe ngovavanyo lokuguguleka, ngokuqhelekileyo kusetyenziswa izinga lokuguguleka ngexesha leyunithi okanye iigram zezinto ezilahlekileyo ngetoni nganye yokuguguleka njengezalathisi zobungakanani. Ukongeza, ukuguda komphezulu kunye nokujikeleza kufuneka kujongwe ukuze kuthintelwe ukuqhekeka, ii-pores, okanye ukuphambuka kwimilo.
