I-Alumina ceramics inokumelana nokuguguleka okuphezulu, ikakhulukazi ngenxa yesakhiwo sayo esincane kanye nezakhiwo zamakhemikhali.
Okokuqala, isakhiwo esincane se-alumina ceramics siyisakhiwo se-polycrystalline esakhiwe yizinhlayiya namaseli, okwenza sibe namandla aphezulu okusebenza. Okwesibili, i-alumina ceramics iyinto enobulukhuni obukhulu kakhulu, ubulukhuni bayo bufana nedayimane, kunzima ukuyigqoka, ngakho-ke inokumelana okuphezulu kokuklwebheka. Okwesithathu, izakhiwo zamakhemikhali ze-alumina ceramics zizinzile kakhulu, cishe ziyamelana nokuguguleka kwawo wonke ama-asidi, izisekelo nosawoti kanye nezinye izinto zamakhemikhali, futhi cishe azithinteki yinoma yiluphi uhlobo lokugqwala kwamakhemikhali.
Izitsha zobumba ze-Alumina zihlukaniswe ngama-grade ahlukene okuhlanzeka, futhi okuqukethwe yi-Al2O3 kuphakeme kuzitsha zobumba ze-alumina zokuhlanzeka okuphezulu. Ngokuvamile, uma okuqukethwe kwe-aluminium kuphakeme, kulapho ukumelana kwayo nokuguguleka kungcono khona.
Ngaphezu kwalokho,izitsha zobumba ze-aluminafuthi inokuqina okuhle kakhulu kokushisa, ingagcina ukusebenza okuhle kakhulu emazingeni okushisa aphezulu, okwenza ukuthi ezimweni eziningi zokusebenza ezingagugi ingadlala ukusebenza okuhle kakhulu.
Ngakho-ke, lezi zici ze-alumina ceramics zizenza zisebenze kahle ezindaweni eziningi lapho kudingeka khona ukumelana nokuguguleka.
