Dab tsi yog cov yam ntxwv thiab cov khoom ntawm mullite?
Mullite yog ib yam khoom zoo heev refractory raw khoom, nws muaj kev nthuav dav, zoo heev thermal shock stability, siab load softening point, tsis kub creep tus nqi, siab hardness, zoo tshuaj corrosion kuj, thiab lwm yam. Tam sim no, muaj mas purity hluav taws xob yaj. mullite, zoo tib yam hluav taws xob yaj mullite, txhua yam ntuj bauxite concentrate sintered mullite thiab lub teeb hlawv mullite.
Mullite yog cov khoom siv zoo refractory. Mullite yog cov ntxhia tsim los ntawm aluminosilicates ntawm qhov kub thiab txias thiab tsim thaum cov khoom cua sov. Ntuj mullite crystals yog elongated koob zoo li thiab radiate nyob rau hauv pawg. Mullite ore yog siv los tsim cov khoom kub kub refractory. Nws yog dav siv los ua thermal barrier txheej hauv C / C cov ntaub ntawv sib xyaw. Mullite AI2O3-SiO2 nyob rau hauv lub atmospheric siab ruaj khov binary khoom tov, tshuaj formula AI2O3-SiO2 natural mullite muaj tsawg heev, feem ntau sintered los yog electrofusion txoj kev thiab lwm yam khoom siv hluavtaws.
