Brown fused alumina tseem hu ua xim av corundum, yog tsim los ntawm melting thiab crystallization ntawm high-zoo raw khoom xws li bauxite thiab anthracite-raws li coke ntawm kub. Cov pob zeb tseem ceeb ntawm cov xim av corundum yog lub cev corundum, trigonal crystal system, thiab cov ntxhia tsis huv yog: calcium silicate, anorthite, mullite (tseem hu ua mullite), titanium compounds, iav lub cev thiab hlau alloys.

Brown fused alumina muaj cov yam ntxwv ntawm siab purity, zoo crystallization, muaj zog fluidity, tsawg coefficient ntawm linear expansion thiab corrosion kuj. Abrasives ua los ntawm nws yog tsim rau kev sib tsoo hlau nrog siab tensile lub zog, xws li carbon steel, dav hlau alloy steel, annealed malleable cam khwb cia hlau thiab nyuaj bronze, thiab lwm yam, thiab kuj yuav siv tau raws li cov ntaub ntawv refractory.
