Ukusetshenziswa kwe-alumina yokuhlanzeka okuphezulu emkhakheni wama-catalysts

I-Alumina iyi-oxide ezinzile ye-aluminium enefomula yamakhemikhali i-Al2O3, okuwuhlobo lwezinto ezingezona ezenziwe ngensimbi. I-alumina iqukethe i-elementaral aluminium ne-oxygen. Uma izinto eziluhlaza ze-bauxite ziphathwa ngamakhemikhali ukususa ama-oxide afana ne-silicon, iron, ne-titanium, umkhiqizo otholiwe uyinto eluhlaza ye-alumina enobumsulwa obuphezulu, futhi okuqukethwe kwe-Al2O3 ngokuvamile kungaphezu kuka-99%.
