Cov khoom tseem ceeb ntawm ceramic fibers feem ntau suav nrog cov hauv qab no:
1. Alumina (Al2O3): Alumina yog cov khoom siv ntawm cov ceramic fibers, muab lub siab melting point thiab zoo heev tshuaj stability. Cov ntsiab lus ntau dua alumina feem ntau ua rau muaj kev kub ntxhov siab dua.
2. Silica (SiO2): Silica yog lwm cov khoom tseem ceeb; ua ke nrog alumina, nws tsim cov fiber ntau lub cev pob txha. Kev suav nrog silica txhim kho cov fiber ntau lub zog thiab ua rau cov tshuaj tiv thaiv corrosion.
3. Zirconia (ZrO2): Zirconia yog cov khoom siv ua haujlwm siab; nws kev koom ua ke rau hauv ceramic fibers ntxiv txhim kho qhov kub thiab txias tsis kam. Lub xub ntiag ntawm zirconia tso cai rau cov fiber ntau kom muaj kev ruaj ntseg nyob rau hauv qhov chaw kub kub.
4. Magnesium Oxide (MgO): Magnesium oxide ua lub stabilizer nyob rau hauv ceramic fibers, kev txhim kho thermal thiab tshuaj stability thaum tseem txhim khu kev siv lub zog.
5. Lwm yam Additives: Ntxiv rau cov khoom tseem ceeb uas tau teev tseg saum toj no, ceramic fibers yuav muaj lwm yam additives xws li calcium oxide (CaO) thiab titanium dioxide (TiO2). Cov additives no tso cai rau kev hloov kho ntawm cov khoom siv fiber ntau-xws li nce thermal poob siab los yog txo qis thermal conductivity-kom tau raws li cov kev cai tshwj xeeb.
