Alumina ceramics rudzi rwezvinhu zveceramic zvine alumina semuviri mukuru. Alumina ceramics ine conductivity iri nani, ine hunyanzvi hwemakanika, inodzivirira kupera uye inodzivirira kupisa kwakanyanya, inozivikanwawo se special ceramics. Al2O3 ceramic material chimiro chakasimba chehexagonal chakagadzirwa ne oxygen ions, uye aruminiyamu ions yakazadzwa muzvikamu zviviri muzvitatu zve octahedral gap, iyo yakafanana ne natural corundum stable structure α-Al2O3, saka ceramic ine poindi yakakwira yekunyunguduka, kuomarara kwakanyanya, uye ine kuramba kupfeka kwakanaka. Kuomarara kweAlumina ceramic ≥HRA85, kuomarara kuri kwechipiri kune diamond, kuramba kwayo kupfeka kwakanaka kwazvo.
Kazhinji, alumina ceramic aruminiyamu yakakamurwa kuita mhando dzakajairika uye mhando dzakachena kwazvo. Zvichienderana nehuwandu hweAl2O3, mhando dzakajairika dzakakamurwa kuita 92% alumina ceramic, 95% alumina ceramic, 96% alumina ceramic. Mhando dzakachena kwazvo i99% alumina ceramic uye pamusoro peceramic, tembiricha yayo inotonhora inosvika 1650-1990℃. 99.7%-99.9% alumina ceramics inogona kushandiswa muindasitiri yemagetsi sebhodhi redunhu rakabatanidzwa uye zvinhu zvekuputira zvine frequency yakawanda, indasitiri yesemiconductor mukugadzira silicon wafers, nezvimwewo, ndiyo sapphire uye semiconductor silicon wafer makemikari ekugadzira polishing kiyi yekutsigira zvikamu uye zvinodyiwa.
Kana zvinhu zvesimbi zvisingapfeki zvealumina zvakakwirira, zvinoita kuti zvinhu zvigadzikane, kureva kuti, kana zvinhu zvesimbi zvealuminamu zvakakwirira, zvinoita kuti zvinhu zvisapfeki zviwedzere. Zvinhu zvesimbi zvealumina sezvinhu zvesimbi zvine hunyanzvi, zvichikurumidza kugadzirwa kwezvinhu zvitsva zvisingapfeki zvemaindasitiri, zvichashandiswa zvakanyanya munharaunda yemazuva ano.
Chemshun Ceramics inopa maceramics akasiyana-siyana e-alumina akachena zvakanyanya, akadai se: 92%Al2O3 & 95%Al2O3 akajairika anodzivirira kusakara kwesimbi, zvidimbu zveceramic lining uye mat, hexagon/square ceramic tile, ceramic pipe/tube/elbow, ceramic cylinder, ceramic block/cube, ceramic brick, 99.7% alumina baseboard uye alumina wafer polishing plate, 99% alumina bulletproof ceramic, nezvimwewo.
