Alumina ceramicsyog ib hom Al2O3 ua cov khoom siv tseem ceeb, corundum (α-al2o3) ua lub ntsiab crystalline theem ntawm cov khoom siv ceramic, tam sim no lub ntiaj teb cov khoom siv oxide ntau heev. Thiab vimalumina ceramicyog ib qho hnav-resistant precision ceramic khoom, nws yog dav siv nyob rau hauv txhua qhov chaw ntawm lub neej.
Alumina ceramicsmuaj cov yam ntxwv ua haujlwm hauv qab no:
1. Hnav tsis kam
Siab purityalumina ceramicsmuaj kev hnav zoo heev, uas yog tsim rau cov khoom siv rau lub sijhawm ntev.
2, tsis muaj deformation
Siab purityalumina ceramicsyog cov ntaub ntawv zoo heev rau precision qhov chaw vim lawv muaj zog dabtsi yog khoov zog thiab compressive zog thiab tsis yooj yim rau kev puas tsuaj.
3, yooj yim los ntxuav
Qhov saum npoo ntawmalumina ceramicsyog du, nws tsis yooj yim rau kev ua raws li impurities, thiab nws yooj yim los ntxuav. Yog li ntawd, nws yog qhov tsim nyog rau kev rov siv dua thiab xav tau kev tu cev hauv kev kho mob.
4, tshuaj tiv thaiv
Alumina ceramicsmuaj zog acid thiab alkali tsis kam rau tshuaj corrosion, thiab tsis tas yuav txhawj xeeb txog tshuaj lom neeg nrog rau lwm yam tshuaj thaum siv.
5, zoo rwb thaiv tsev
High purity alumina ceramic yog cov khoom siv insulating zoo heev vim tsis muaj impurities, nws muaj peev xwm tiv taus qhov hluav taws xob raws li cov khoom siv insulating, tsawg ntim efficiency, txawm tias kub kub los tswj cov rwb thaiv tsev, thiab cov cua sov zoo heev.
6, plasma tsis kam
Vim lub siab purity ntawm alumina ceramics (Al 2 O 3 > 99.9%) thiab yuav luag tsis muaj intergranular segregation thiab, yog li ntawd, yog siv raws li ib tug anti-plasma khoom.
Hauv cov ntsiab lus, muaj qee qhov kev ua tau zoo ntawm alumina ceramics. Alumina ceramics muaj txoj haujlwm siab hauv kev ua haujlwm ntawm cov khoom siv ceramic, thiab tau siv dav hauv electronics, khoom siv hluav taws xob, tshuab, textiles, aerospace thiab lwm yam kev lag luam.
