Nyob rau hauv cov nqe lus ntawm qhov loj thiab ntshiab txhuas oxide cov ntsiab lus, aluminium oxide ceramic yog cov feem ntau technical ceramics. Aluminium oxide, tseem hu ua Alumina, yuav tsum yog thawj ceramic uas tus tsim qauv saib yog tias nws tab tom xav txog kev siv cov ceramics los hloov cov hlau los yog cov hlau tsis tuaj yeem siv vim qhov kub siab, tshuaj lom neeg, hluav taws xob, lossis hnav. Tus nqi ntawm cov khoom tom qab nws tau raug rho tawm haujlwm tsis yog siab heev, tab sis yog tias xav tau kev zam kom raug, pob zeb diamond sib tsoo thiab polishing yog xav tau, uas tuaj yeem ntxiv cov nqi ntau thiab ua rau feem ntau kim dua ib feem hlau. Cov nyiaj khaws cia tuaj yeem los ntawm lub neej ntev dua lossis tsawg dua lub sijhawm uas lub kaw lus yuav tsum tau coj mus rau offline kom kho lossis hloov pauv. Tau kawg, qee qhov kev tsim qauv tsis tuaj yeem ua haujlwm tag nrho yog tias lawv nyob ntawm cov hlau vim yog ib puag ncig lossis cov kev xav tau ntawm daim ntawv thov.
Tag nrho cov ceramics feem ntau yuav tawg dua li cov hlau feem ntau, uas yog ib yam uas tus tsim qauv yuav tsum xav txog. Yog tias koj pom tias Alumina yooj yim rau nti lossis tawg hauv koj daim ntawv thov, Zirconium oxide ceramic, tseem hu ua Zirconia, yuav yog lwm txoj hauv kev zoo los saib. Nws kuj yog ib qho nyuaj heev thiab resistant rau hnav. Zirconia muaj zog heev vim nws qhov tshwj xeeb tetragonal siv lead ua qauv, uas feem ntau yog tov nrog Yttria. Zirconia cov nplej me me ua rau cov neeg tsim khoom tuaj yeem ua cov ntsiab lus me me thiab cov npoo ntse uas tuaj yeem sawv ntsug rau kev siv ntxhib.
Ob qho tib si ntawm cov khoom siv raw no tau pom zoo rau qee qhov kev kho mob thiab siv hauv lub cev nrog rau ntau yam kev lag luam. Cov neeg tsim khoom ntawm cov khoom siv ceramic rau siv hauv kev kho mob, aerospace, semiconductor, instrumentation, thiab industrial applications yog txaus siab rau peb cov kws tshaj lij hauv kev tsim khoom.
