Yiziphi izici zokusebenza ze-alumina ceramics?

I-Alumina Ceramicsiwuhlobo lwe-Al2O3 njengento eluhlaza eyinhloko, i-corundum (α-al2o3) njengesigaba sekristalu esiyinhloko sezinto zobumba, okwamanje inani elikhulu kakhulu lomhlaba lezinto ze-oxide ceramic. Futhi ngobai-alumina ceramiciyimpahla ye-ceramic enembayo engagugi kakhulu, isetshenziswa kabanzi kuzo zonke izigaba zokuphila.

I-Alumina Ceramicsbabe nezici zokusebenza ezilandelayo:

1. Ukumelana nokugqoka

Ukuhlanzeka okuphezului-alumina ceramicsube nokumelana okuhle kakhulu kokugqoka, okulungele izingxenye ezisetshenziswe isikhathi eside.

2, akukho deformation

Ukuhlanzeka okuphezului-alumina ceramicsziyizinto ezinhle kakhulu zezingxenye ezinembayo ngoba zinamandla okugoba aqinile namandla acindezelayo futhi akulula ukuzilimaza.

3, kulula ukuhlanza

Ubuso bei-alumina ceramicsibushelelezi, akulula ukunamathela kukungcola, futhi kulula ukuyihlanza. Ngakho-ke, kufanelekile ukusetshenziswa kabusha kanye nesidingo sokugcina inhlanzeko emkhakheni wezokwelapha.

4, ukumelana namakhemikhali

I-Alumina Ceramicsbabe ne-asidi eqinile ne-alkali ukumelana nokugqwala kwamakhemikhali, futhi asikho isidingo sokukhathazeka mayelana nokusabela kwamakhemikhali nezinye izidakamizwa ngesikhathi sokusetshenziswa.

5, ukwahlukanisa okuhle

Ukuhlanzeka okuphezulu kwe-alumina ceramic kuyinto enhle kakhulu yokuvikela impahla ngenxa yokungcola okuphansi, inamandla okumelana ne-voltage njenge-insulating material, ukusebenza kahle kwevolumu ephansi, ngisho nasemazingeni okushisa aphezulu ukugcina ukufakwa, kanye nokumelana nokushisa okuhle kakhulu.

6, ukumelana ne-plasma

Ngenxa yokuhlanzeka okuphezulu kwe-alumina ceramics (Al 2 O 3> 99.9%) futhi cishe ayinakho ukuhlukaniswa kwe-intergranular futhi, ngakho-ke, isetshenziswa njengento elwa ne-plasma.

Kafushane, kunezici ezithile zokusebenza ze-alumina ceramics. I-alumina ceramics inesikhundla esiphakeme emkhakheni wezinto zobumba, futhi isetshenziswa kabanzi ezintweni zikagesi, izinto zikagesi, imishini, izindwangu, i-aerospace kanye neminye imikhakha.
