99% alumina ceramics, nrog lawv lub zog siab, siab tawv thiab tshuaj lom neeg tsis muaj zog hauv ntau qhov chaw, tuaj yeem siv tau zoo hauv kev tiv thaiv mos txwv. Cov ceramics tiv thaiv mos txwv thiab cov phaj sib xyaw ua ke muaj zog thiab fiber ntau modulus ua ke tsim cov txheej tiv thaiv mos txwv. Thaum lub mos txwv ceev ceev sib tsoo nrog txheej ceramic, txheej ceramic tawg lossis tsim cov kab nrib pleb uas nthuav tawm ntawm qhov chaw nruab nrab, siv feem ntau ntawm lub zog ntawm lub mos txwv. Tom qab ntawd, cov phaj sib xyaw ua ke fiber ntau modulus siv lub zog seem ntawm lub mos txwv.
Cov txheej txheem nqus zog ntawmcov khoom siv ua los ntawm cov khoom siv av nplaum uas tiv taus cov mos txwvmuaj peev xwm faib ua peb theem:
① Theem pib ntaus: Lub mos txwv ntaus rau ntawm qhov chaw ceramic, ua rau lub taub hau mos txwv tsis ci ntsa iab thiab tawg ua tej daim me me thiab tawv rau ntawm qhov chaw ceramic.
② theem kev tawg: Lub mos txwv blunted txuas ntxiv mus tawg thaj chaw tawg, tsim ib txheej txuas ntxiv ntawm cov khoom siv ceramic.
③ Theem kev hloov pauv, kev tawg thiab kev tawg: Thaum kawg, kev ntxhov siab tensile raug tsim nyob rau hauv lub ceramic, ua rau nws tawg. Thaum lub sijhawm ntawm lub mos txwv ntaus lub ceramic, ob qho tib si lub mos txwv thiab lub ceramic raug puas tsuaj.
Ib qho zoo ntawm cov khoom siv ceramic uas tiv taus mos txwv dua li cov hlau yog tias cov khoom siv hlau hloov pauv yas thiab nqus lub zog thaum tiv taus qhov cuam tshuam ntawm lub taub hau mos txwv. Yog tias hnav rau ntawm tib neeg lub cev, qhov kev hloov pauv yas no yuav ua rau tib neeg lub cev raug mob. Cov khoom siv ceramic uas tiv taus mos txwv tsis tshua hloov pauv yas.
Yog li ntawd, daim ntawv thov ntawm cov khoom siv ceramics siab heev hauv cov txheej txheem ua rog yog qhov txaus nyiam heev thiab tau dhau los ua cov cuab yeej tiv thaiv dav dav rau cov khoom siv xws li cov tsho tiv thaiv mos txwv, tsheb, thiab dav hlau.
