High purity alumina hmoov, tseem hu ua alumina, nrog molecular hnyav ntawm 102, yog ib tug dawb amorphous hmoov, feem ntau hu ua bauxite
Alumina (Al2O3) yog cov hmoov zoo dawb uas muaj purity ntau dua 99.99% los ua alumina siab purity
Alumina siv hauv catalysts feem ntau yog tshwj xeeb hu ua "activated alumina".Nws yog ib qho ntxeem tau thiab cov khoom tawg yooj yim heev nrog thaj tsam loj.Nws cov microporous nto muaj cov yam ntxwv xav tau rau catalysis, xws li kev ua haujlwm adsorption, kev ua haujlwm saum npoo, zoo thermal stability, thiab lwm yam.
Nano alumina yog ib qho inorganic tshuaj nrog cov tshuaj formula ntawm Al2O3thiab dawb crystalline hmoov α , β , γ , δ , η , θ , κ thiab χ Kaum ib hom muaju.
