Hnav cov kav dej ceramic uas tiv tausyog cov khoom tseem ceeb rau kev sib txuas ntawm cov kav dej thiab kev hloov pauv ntawm kev coj ua. Txawm li cas los xij, txij li thaum cov ntaub ntawv xa mus hloov pauv ntawm lub luj tshib, lub luj tshib yuav tsum tiv taus qhov cuam tshuam loj thiab hnav. Kev hnav ntawm cov luj tshib kev lag luam yeej ib txwm yog qhov tseem ceeb uas cuam tshuam rau kev nyab xeeb ntawm kev tsim khoom. Cov khoom siv luj tshib tau dhau los ua pob zeb cam khwb cia, hlau cam khwb cia, hlau sib xyaw thiab lwm yam khoom siv. Ntawm lawv, cov kav dej hauv alumina ceramic tau dhau los ua qhov kev xaiv ntawm feem ntau cov lag luam hnav hnyav nrog nws qhov kev tiv taus hnav siab, qhov nyuaj siab, kev tiv taus oxidation, kev tiv taus corrosion zoo, qhov hnyav sib dua thiab lub zog kub siab thiab qis heev.
Qhov zoo ntawm cov lauj kaub ceramic uas tsis yooj yim puas yog feem ntau pom tseeb hauv kev tiv taus kev hnav zoo heev, tiv taus kev yaig muaj zog, tiv taus kev xeb zoo heev thiab lub neej ntev. Qhov nyuaj ntawm cov lauj kaub ceramic uas tsis yooj yim hnav yog siab dua li cov khoom siv hlau ib txwm muaj. Nws tuaj yeem tiv taus kev yaig ntawm cov kua dej ceev ceev thiab kev hnav cov khoom khov kho, txo qhov hnav ntawm cov kav dej, thiab ntev lub neej kev pabcuam.
Hais txog kev siv, cov lauj kaub ceramic uas tsis hnav tau siv dav hauv kev tsuas, metallurgy, fais fab, tshuaj lom neeg thiab lwm yam lag luam. Hauv kev lag luam tsuas, cov lauj kaub ceramic uas tsis hnav tau tuaj yeem tiv taus kev txhuam ceev thiab kev hnav ntawm cov khoom khov xws li ore thiab thee, uas ua rau lub neej kev pabcuam ntawm cov kav dej zoo dua. Hauv kev lag luam fais fab thiab metallurgy, cov lauj kaub ceramic uas tsis hnav tau siv rau hauv cov kav dej tshem tawm tshauv thiab slag hauv cov chaw tsim hluav taws xob thee, nrog rau kev thauj cov kua hauv cov cub tawg, cov hloov pauv thiab lwm yam khoom siv, qhia tau tias lawv muaj peev xwm tiv taus qhov kub siab, siab siab thiab cov kua dej corrosive.
Cov lauj kaub ceramic uas tsis yooj yim hnav tau dhau los ua qhov tseem ceeb thiab tseem ceeb hauv cov khoom siv hauv kev lag luam vim lawv qhov kev tiv thaiv kev hnav zoo heev thiab cov teb siv dav.
