Mullite Brick ke mofuta oa High-aluminium refractories e nkang mullite (Al2O3• SiO2) e le karolo e ka sehloohong ea kristale. Tekanyo e tloaelehileng ea aluminium e pakeng tsa 65% le 75%. Ho phaella ho mullite mineral composition, e nang le alumina e tlaase e boetse e na le likhalase tse nyenyane le cristobalite; alumina e phahameng e nang le palo e nyane ea corundum. Refractoriness e phahameng ho fihlela ho 1790 ° C. Ho nolofatsa moroalo ho qala mocheso 1600 ~ 1700 °C. Mocheso oa kamore o hatella matla a 70 ~ 260MPa. Ho hanyetsa mocheso o motle oa mocheso. Setene sa mullite se amohela poleiti ea corundum e tsoang kantle ho naha le corundum ea boleng bo holimo e le thepa ea mantlha, 'me e sebelisa theknoloji e tsoetseng pele ea ho eketsa phofo ea ultrafine. Ka mor'a ho kopanya, ho omisa le ho theha, e chesoa ka sebōping sa shuttle se nang le mocheso o phahameng.
