Iiceramics zeAlumina luhlobo lweeceramics zobunjineli, kwaye ukusetyenziswa kwemihla ngemihla kweemveliso zeceramic kwahlukile kakhulu. Iiceramics zeAlumina zikwaziwa njengeeramics ezingagugiyo, kuba zinokugugika kakuhle, ziyamelana nokugqwala, ziyamelana nobushushu obuphezulu, ngoko ke zisetyenziswa kakhulu kwintsimbi, amalahle, imigodi, isamente, iikhemikhali kunye neminye imimandla, lukhetho olufanelekileyo lokumelana nokugugika kwimizi-mveliso.
Inkqubo yokwenza iiseramikhi ze-alumina ngokubanzi yahlulwe ngamanyathelo aliqela: ukulungiswa komgubo, ukucinezela, ukuthulula.
Ukuze kwenziwe iiseramikhi ezingagugiyo nezisebenza kakuhle, kuyimfuneko ukukhetha umgubo we-alumina olungileyo, onobukhulu beesuntswana obuhlala buyi-1μm okanye ngaphantsi. Kwinkqubo yokulungiselela umgubo, kufuneka kongezwe izongezo ezahlukeneyo ukulungiselela umgubo oneempawu ezahlukeneyo.
Iiseramikhi zeAlumina zinokwenziwa ngeendlela ezahlukeneyo. Iindlela ezisetyenziswa kakhulu zezi: ukubumba ngokucinezela okomileyo, ukubumba nge-grouting, i-extrusion, ukubumba ngokucinezela nge-isostatic, indlela yokufaka inaliti, indlela yokuqengqeleka, indlela yokucinezela ngobushushu, indlela yejeli, njl. Ukubonelela ngokubumba ngundoqo wokulungiselela iiseramikhi ezinganyangekiyo ngokunxiba ezisebenza kakuhle. Ngokubanzi, iiseramikhi zeAlumina ezenziwe ngokucinezela okomileyo kunye nenkqubo yokucinezela nge-isostatic zinobunzima obuphezulu kunye nokumelana nokuguguleka.
Ukusila i-alumina ceramics nako kuyinyathelo elibaluleke kakhulu. Phakathi kwazo, ulawulo lobushushu bokusila yeyona nto iphambili, nto leyo emisela uxinano, ulwakhiwo kunye nobomi benkonzo ye-ceramic.
Inyathelo ngalinye lemvelisoiiseramikhi ze-aluminaifuna ulawulo kunye nokufunyanwa kobuchwephesha, ukuze ifumane iiseramikhi ezibalaseleyo ezingagugiyo.
