Vim hais tias andalusite, sillimanite thiab kyanite hloov mus rau hauv mullite ntawm qhov kub, thiab nthuav cov coefficient ntawm mullite yog me me, nws tau txais txiaj ntsig los txhim kho cov thermal shock tsis kam ntawm cov khoom siv. Qhov sib ntxiv ntawm andalusite mus rau cov khoom siv tuaj yeem ua ntau qhov zoo ntawm lub tshav kub tiv thaiv kev ntxhov siab, uas tuaj yeem tso tawm qhov kev ntxhov siab nyob rau sab hauv ntawm qhov refractory vim yog nthuav thiab tsis sib haum, yog li txhim kho lub thermal poob siab ntawm cov khoom. Qhov kub ntawm ua tiav Mullitization ntawm sillimanite yog siab dua, uas yog qhov zoo rau kev txhim kho qhov siab kub creep tsis kam ntawm cov khoom. Tsis tas li ntawd, qhov ntim nthuav tawm ntawm Mullitization tseem tau txais txiaj ntsig zoo li cov nkag ntawm qhov kub.
Nws tau taw qhia tias qhov nkag ntawm lub pob zeb andalusite zoo dua li ntawm cov qib siab alumina cib, corundum cib thiab feem ntau mullite cib. Yog li ntawd, kev txhim kho thiab siv ntawm" peb lub pob zeb" txhawm rau txhim kho cov microstructure thiab thermodynamic cov khoom ntawm Al Si refractories muaj qhov chaw zoo thov.
