Alumina ine aruminiyamu yakawandamabhora ekukuya e alumina ceramicZvinhu zvekugadzira zveceramic zveinjiniya zvemhando yepamusoro zvinoumbwa nealuminium oxide (Al₂O₃), zvinowanzova nehukuru hunopfuura 90%. Zvinoratidza kuomarara kwakanyanya, kuramba kupfeka kwakanyanya, kugadzikana kwakanyanya kwemakemikari, uye kusvibiswa kwakaderera, zvichiita kuti zvishandiswe zvakanyanya mumabasa ekukuya akanyorova kana akaoma kumaindasitiri akadai seceramics, pendi, makemikari, migodhi, uye zvinhu zvemagetsi. Nehuwandu hwazvo hunowanzova pamusoro pe3.6 g/cm³ uye kuomarara kweVickers kusvika kuHV1500 kana kupfuura, zvinowedzera kushanda zvakanaka kwekukuya uku zvichideredza kushandiswa kwemedia.
Zvakanakira zvikuru zviri mukuvandudza kushanda zvakanaka kwekukuya uye kushanda zvakanaka kwehupfumi. Kuomarara kwakanyanya (Mohs grade 9) kunoita kuti zvinhu zvakaoma zvipwanyike nekukurumidza; chimiro chakafanana chinopa mwero wekupfekwa nguva dzose uye chinoenderera mberi nehupenyu hwebasa. Kusashanda zvakanaka kwemakemikari kunobvumira kuramba maacid akasimba uye alkalis, zvichidzivirira kusvibiswa kwezvinhu zvevhu. Zvisikwa zvesimbi zvishoma (zvinowanzova pasi pe0.01%) zvinoita kuti zvive zvakakodzera kushandiswa pakuchenesa, senge zvinhu zvebhatiri re lithium, magirazi epamusoro, uye ceramics dzemagetsi.
Maitiro ekugadzira anosanganisira kugadzirira hupfu hwakanyatsodzorwa, kudzvanya kwe isostatic, uye kupisa kwakanyanya kuti pave nekusimba kwakanyanya, kuve nechokwadi chekuti porosity yakaderera uye kusimba kwakanyanya kwekupwanyika. Kuongorora mhando kunosanganisira kururamisa mativi, sphericity, kuomarara, uye kuramba kukanganiswa kuti zvienderane nezvinodiwa zvemidziyo yakasiyana-siyana yekukuya nemamiriro ekushanda. Kusarudzwa kwakakodzera kwezvinotsanangurwa (semuenzaniso, dhayamita kubva pa1mm kusvika 50mm) uye zviyero zvekuzadza zvinogona kuwedzera kunaka kwekukuya uye kushanda zvakanaka kwesimba.
Nekuwedzera kwekuda kwehukuru hwezvimedu zvakapfava uye kuchena kwakanyanya mukuvandudza maindasitiri, mabhora ekukuya ane alumina yakawanda ave chinhu chakakosha muzvikamu zvemakemikari nemidziyo mitsva yemazuva ano. Nekuwedzera kunaka kwechigadzirwa uye kuderedza mitengo yese, anopa mhinduro yakavimbika yehunyanzvi kumaindasitiri ekugadzirisa nemazvo. Mune ramangwana, kugadzirisa mafomati emidziyo uye kufambira mberi muhunyanzvi hwekugadzirisa pamusoro penzvimbo zvichawedzera mukana wekushandisa.
