I-aluminiyam oxide yifomula yekhemikhali ye-alumina, into eyenziwe nge-aluminiyam kunye ne-oxygen. Ibizwa ngokuchanekileyo njenge-aluminiyam oxide kwaye yeyona nto ixhaphakileyo kwezinye ii-aluminiyam oxides. Ukongeza ekubeni yaziwa ngokuba yi-alumina, inokuphinda ihambe ngamagama e-aloxide, i-aloxite, okanye i-alundum, kuxhomekeke kwimo kunye nokusetyenziswa kwayo. Eli nqaku ligxile kwisicelo se-alumina kwintsimi ye-ceramic.

Isikrweqe

Ezinye izikrweqe zomzimba zisebenzisa iipleyiti ze-alumina ceramic, eziqhele ukudibana ne-aramid okanye inkxaso ye-UHMWPE, ukufumana ukusebenza kakuhle ngokuchasene nezoyikiso zompu. Nangona kunjalo, ayithathwa njengomgangatho womkhosi. Ukongeza, inceda ukuqinisa iglasi ye-alumina ngokuchasene nefuthe leembumbulu ze-.50 BMG.

Izicelo zeBiomedical

Icandelo le-biomedical lisebenzisa kakhulu i-alumina ceramics ngenxa ye-biocompatibility ephezulu kunye nokuqina ngokuchasene nokuguga kunye nokubola. I-alumina ceramic isebenza njengesixhobo sokufakelwa kwamazinyo, ukutshintshwa ngokudibeneyo, kunye nezinye izixhobo zonyango.

Abrasive

Uninzi lwezixhobo zokuqhafaza kwimizi-mveliso zihlala zisebenzisa i-alumina ngenxa yamandla ayo akhethekileyo kunye nokuqina. Kwisikali se-Mohs sobunzima beeminerali, ifom yendalo eyenzeka ngokwemvelo, i-corundum, ixabisa i-9-ngaphantsi kwedayimane. Ngokufana nedayimani, umntu unokwambathisa i-alumina ukuthintela ukuqhawuka. Abenzi bewotshi kunye nabenzi beewotshi basebenzisa i-Diamantine, kwifom yayo ecocekileyo yomgubo (emhlophe), njenge-abrasive yokupholisha ephezulu.

Ukugquma

I-Alumina sisigqumatheli esigqwesileyo, esenza ukuba ilungele ukusetyenziswa kubushushu obuphezulu kunye nezicelo zombane ophezulu. Isetyenziswe njenge-substrate (i-silicon kwisafire) kunye nomqobo wetonela kwiisekethe ezidibeneyo ukwenza izixhobo eziphezulu ze-superconducting ezifana ne-transistors enye ye-electron, i-superconducting quantum interference devices (SQUIDs), kunye ne-superconducting qubits.

Ukusila

Icandelo le-ceramics likwasebenzisa i-alumina njengendawo yokusila. I-alumina yeyona nto ifanelekileyo yokusebenzisa kwizicelo zokusila ngenxa yokuqina kwayo kunye nokumelana nokunxiba. Izingqusho zebhola, ii-vibratory Mills, kunye nabanye oomatshini bokusila basebenzisa i-alumina njengendawo yokusila.

Ukuqukumbela

Nangona i-alumina isaziwa ngokuyintloko ngokusetyenziswa kwayo kwimveliso ye-aluminiyam, ikwabambe ukubaluleka okubalulekileyo kumasimi amaninzi e-ceramic. Yimpahla efanelekileyo kwezi zicelo ngenxa yendawo ephezulu yokunyibilika, iimpawu ezibalaseleyo ze-thermal kunye ne-mechanical properties, i-insulating properties, ukumelana nokunxiba, kunye ne-biocompatibility.
