Txawm hais tias mullite muaj raws li cov ntxhia hauv ntuj, qhov tshwm sim hauv qhov xwm txheej yog qhov tsawg heev.
Kev lag luam cia siab rau cov khoom siv hluavtaws uas tau ua tiav los ntawm melting lossis 'calcining' ntau yam alumino-silicates xws li kaolin, av nplaum, tsis tshua muaj andalusite lossis nplua silica thiab alumina kom kub.
Ib qho zoo tshaj plaws ntuj qhov chaw ntawm mullite yog kaolin (raws li kaolinic av nplaum).Nws yog qhov zoo tshaj plaws rau kev tsim cov refractories xws li raug rho tawm haujlwm lossis tsis muaj hluav taws kub, castables thiab cov yas sib tov.
Sintered mullite thiab fused mullite feem ntau yog siv rau kev tsim cov refractories thiab casting steel thiab titanium alloys.
