Taageerada kicinta alfa alumina

Sharaxaad Gaaban:

α-Al2O3 waa wax daloola, kaas oo inta badan loo isticmaalo in lagu taageero kicinta, adsorbents, qalabka gaaska kala soocida, iwm. Cabbirka daloolka ee α-Al2O3 qaadaha kicinta ayaa aad uga weyn jidka bilaashka ah ee molecular, iyo qaybintu waa mid isku mid ah, sidaas darteed dhibaatada faafinta gudaha ee ay sababtay xajmiga yar yar ee habka falcelinta catalytic ayaa si fiican loo tirtiri karaa, iyo falcelinta dhinaca oksaydhka qoto dheer ayaa la dhimi karaa habka ujeedada loo yaqaan 'oxidation'. Tusaale ahaan, kicinta qalinka ah ee loo isticmaalo oxidation ethylene ilaa ethylene oxide waxay isticmaashaa α-Al2O3 sida side. Inta badan waxaa loo adeegsadaa falcelinta kicinta leh heerkulka sare iyo xakamaynta faafinta dibadda.
