Cov tshuaj lom neeg ntawm mullite yog 3Al2O3.2SIO2, thiab cov ntsiab lus theoretical yog 71.8% Al2O3 thiab 28.2% SiO2. Cov khoom cua mullite feem ntau yog sintered thiab fused. Cov khoom siv mullite hluavtaws yog cov khoom siv hluav taws xob zoo nrog cov yam ntxwv ntawm kev nthuav dav ib txwm muaj, zoo thermal poob siab ruaj khov, siab ua kom sov ua kom sov, qhov kub me me cuam tshuam tus nqi, siab tawv thiab ua haujlwm zoo tshuaj lom neeg xeb
Cov ntaub ntawv raw siv rau kev sib xyaw ntawm mullite los ntawm txoj kev sintering suav nrog kev lag luam alumina, pyrogem, kaolin, silica thiab bauxite. Cov txheej txheem sib sau ua ke yog muab cov khoom tso rau hauv lub pob zeb rau kev sib tsoo thiab sib xyaw, nias pob lossis khoob, thiab tom qab ntawd hlawv nws hauv lub qhov cub tawg lossis lub qhov cub. Cov ntaub ntawv raw rau kev sib xyaw mullite los ntawm txoj kev siv hluav taws xob suav nrog kev lag luam alumina, bauxite thiab silica. Cov txheej txheem electrofusion yog txhawm rau tsoo cov silica thiab bauxite kom tsawg dua 1.5 hli, sib tov lawv sib npaug nrog lwm cov hmoov, thiab tom qab ntawd yaj lawv rau hauv hluav taws xob rauv. Kev txo qis huab cua tau tswj hwm hauv lub tshuab hluav taws xob kom tshem tawm cov khoom tsis huv xws li hlau oxide, TiO2, CaO, R2O, thiab lwm yam
