Tsawg Expansion Fused Mullite Rau iav Ceramic Composites

Tsawg expansion fused mullite yog ib hom khoom siv uas feem ntau siv hauv iav-ceramic composites. Mullite yog cov ntxhia uas muaj li ntawm alumina thiab silica, thiab nws paub txog nws qhov siab melting point thiab qis thermal expansion coefficient. Fused mullite yog tsim los ntawm melting thiab ces sai txias alumina thiab silica raw cov ntaub ntawv. Cov txheej txheem no ua rau muaj cov khoom siv ntshiab thiab ntom ntom heev uas muaj cov khoom siv kho tshuab, thermal, thiab tshuaj lom neeg.

Tsawg expansion fused mullite yog tshwj xeeb tshaj yog pab tau nyob rau hauv iav-ceramic composites vim nws tsis tshua muaj thermal expansion coefficient, uas txhais tau hais tias nws muaj peev xwm tiv taus thermal shock thiab kub hloov tsis muaj cracking los yog tawg. Cov cuab yeej no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv nyob rau hauv qhov chaw kub thiab kub hloov pauv sai, xws li hauv cov rooj tog zaum, refractories, thiab ua ib qho substrate rau cov khoom siv hluav taws xob.

Hauv cov iav-ceramic composites, qis expansion fused mullite feem ntau yog siv los ua cov khoom siv ntxiv los txhim kho lub zog thiab thermal stability ntawm cov khoom sib xyaw. Cov mullite fibers yog tov nrog iav matrix thiab ces rhuab mus rau ib tug kub kub los ua ib tug iav-ceramic composite khoom. Cov khoom siv tau zoo heev thermal thiab mechanical zog, thiab yog siv nyob rau hauv ntau yam kev siv xws li cookware, kho hniav cov ntaub ntawv, thiab high-kev ua tau zoo insulators.
