Iiseramics ze-alumina luhlobo lwe-Al2O3 njengeyona nto iphambili, i-corundum (α-al2o3) njengenqanaba lekristale eliphambili lezinto ze-ceramic, okwangoku ubuninzi behlabathi bezinto ze-oxide ze-ceramic.Kwaye ngenxa yokuba i-alumina ceramic iyimathiriyeli ye-ceramic engagugi kakhulu, isetyenziswa kakhulu kuzo zonke iindlela zobomi.
Iiseramikhi zealumina zineempawu zokusebenza ezilandelayo:
1. Ukunxiba ukuxhathisa
Ucoceko oluphezulu lwe-alumina ceramics lunokunganyangeki okuhle kakhulu, olulungele iindawo ezisetyenziswa ixesha elide.
2, akukho deformation
Ucoceko oluphezulu lwe-alumina ceramics zizixhobo ezigqwesileyo zeendawo ezichanekileyo kuba zinamandla okugoba kunye namandla acinezelayo kwaye akukho lula ukuwonakalisa.
3, kulula ukuyicoca
Umphezulu we-alumina ceramics ugudile, akulula ukuthobela ukungcola, kwaye kulula ukuyicoca.Ngoko ke, ifanelekile ukusetyenziswa kwakhona kunye nesidingo sokugcina ucoceko kwintsimi yezonyango.
4, ukuxhathisa imichiza
Iiseramikhi ze-alumina zine-asidi eyomeleleyo kunye nokumelana ne-alkali kwi-corrosion yekhemikhali, kwaye akukho mfuneko yakukhathazeka malunga nokusabela kweekhemikhali kunye namanye amachiza ngexesha lokusetyenziswa.
5, ukugquma kakuhle
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 kwe-alumina ceramics (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.
