Cov txheej txheem tsim khoom siv cov txheej txheem kub kub melting, uas yog tsim cov kua lava ntawm qhov kub ntawm ze li ntawm 2000 degrees rau hauv cov khoom hauv ob peb feeb. Lub microstructure ntawm cov khoom tsim nyob rau hauv no quenching mob yog heev txawv los ntawm cov khoom ua ntej melting ntawm raw cov ntaub ntawv.
Vim yog lub zog ceev ceev ntawm cov kua kub kub, qhov txias txias yog nrawm dua li qhov sib txawv ntawm qhov sib txawv hauv cov khoom siv microstructure, yog li tsis muaj cov xwm txheej rau cov txheej txheem ntawm lattice tsim thiab kev npaj, kom cov microstructure nyob rau hauv cov khoom. tsim cov qauv tsis ruaj khov, uas yog, cov khoom nyob hauv lub xeev metastable. Lub xeev metastable khoom no khaws ib lub zog muaj peev xwm. Nyob rau hauv tej yam kev mob (piv txwv li, thaum kub nce, nws tsim tej yam kev mob rau atomic diffusion), nws yuav tso nws lub zog sab hauv thiab hloov mus rau hauv ib tug ruaj khov lub koom haum qauv. Thawj kauj ruam ntawm kev hloov pauv yog tias cov atoms pib rov ua dua nyob rau hauv lub khob iav, uas yog, crystallization lossis crystallization.
Raws li cov ntsiab lus ntawm alumina thiab cov khoom siv thib peb ntxiv rau inhibit crystallization ntawm qhov kub thiab txias, ceramic fiber board tuaj yeem muab faib ua tsib pawg: zoo tib yam ceramic fiber board, txheem ceramic fiber board, siab purity ceramic fiber board, siab alumina ceramic fiber board. thiab zirconium-muaj ceramic fiber board (chromium-muaj ceramic fiber).
