Iiseramikhi zealuminaluhlobo lwe-Al2O3 njengeyona nto iphambili, i-corundum (α-al2o3) njengeyona nxalenye iphambili yekristale yezinto ze-ceramic, okwangoku isixa esikhulu sehlabathi se-oxide ye-ceramic materials. Kwaye ngenxa yokubaalumina ceramicyimathiriyeli ye-ceramic echanekileyo enganxibi kakhulu, isetyenziswa kakhulu kuzo zonke iinkalo zobomi.
Iiseramikhi zealuminabaneempawu zokusebenza ezilandelayo:
1. Ukunxiba ukuxhathisa
Ukucoceka okuphezuluiiseramikhi zealuminaube nokumelana nokunxiba okuhle kakhulu, okufanelekile kumalungu asetyenziswa ixesha elide.
2, akukho deformation
Ukucoceka okuphezuluiiseramikhi zealuminazizixhobo ezigqwesileyo zamalungu achanekileyo kuba zinamandla okugoba aqinileyo kunye namandla acinezelayo kwaye akukho lula ukonakalisa.
3, kulula ukuyicoca
Umphezulu weiiseramikhi zealuminaigudile, akulula ukubambelela kukungcola, kwaye kulula ukuyicoca. Ngoko ke, ifanelekile ukusetyenziswa kwakhona kunye nesidingo sokugcina ucoceko kwintsimi yezonyango.
4, ukuxhathisa imichiza
Iiseramikhi zealuminaube ne-asidi eyomeleleyo kunye nokumelana ne-alkali kwi-corrosion yeekhemikhali, kwaye akukho mfuneko yakukhathazeka malunga nokusabela kweekhemikhali kunye namanye amachiza ngexesha lokusetyenziswa.
5, ukugquma okulungileyo
Ucoceko oluphezulu lwe-alumina ceramic sisixhobo esihle kakhulu sokugquma ngenxa yokungacoceki okuphantsi, inamandla okumelana nombane njengesixhobo sokugquma, ukusebenza kakuhle komthamo ophantsi, nokuba kubushushu obuphezulu bokugcina ubushushu, kunye nokumelana nobushushu.
6, ukuxhathisa iplasma
Ngenxa yokucoceka okuphezulu kweekeramics ze-alumina (Al 2 O 3> 99.9%) kwaye phantse akukho ukuhlukana kwe-intergranular kwaye, ngoko ke, isetyenziswe njengento echasene ne-plasma.
Isishwankathelo, kukho ezinye iimpawu zokusebenza ze-alumina ceramics. I-alumina ceramics inesikhundla esiphezulu kwintsimi yezinto ze-ceramic, kwaye isetyenziswa ngokubanzi kwi-electronics, izixhobo zombane, oomatshini, iingubo, i-aerospace kunye nezinye iindawo.
