BROWN FUSED Alumina

Brown Fused Alumina(BFA) yog cov khoom siv refractory uas yog tsim los ntawm smelting thiab refinement ntawm Calcined Bauxite nyob rau hauv ib tug hluav taws xob arc rauv los yog tsau rauv ntawm kub siab tshaj 2000 degree. Nws tseem hu ua electro corundum, xim av corundum thiab xim av aluminium oxide, tau txais cov ntxhia pob zeb thaum sib xyaw. Cov khoom tseem ceeb yog alumina Al₂O₃. Nws muaj cov yam ntxwv zoo crystallization, zoo toughness, tsis tshua muaj linear expansion coefficient, thiab corrosion kuj. Ua ke nrog qhov zoo ntawm purity siab, ecologically huv thiab tsis tshua muaj zog cov ntaub ntawv, Brown fused alumina yog dav siv nyob rau hauv zus tau tej cov abrasives, refractory thiab nyob rau hauv qhuav- thiab ntub-blasting daim ntaub ntawv qhov twg nws yog reusable. Meanwhile, Brown fused alumina yog dawb ntawm tsis respirable crystalline silica (SiO₂).
