I-alumina eyenziwe yasebenza ngeendlela ezincinci, ke umphezulu othile mkhulu. Ingasetyenziselwa njenge-adsorbent, desiccant, defororinating agent kunye ne-catalyst carrier. Ikwaluhlobo lokulandela umkhondo wamanzi e-desiccant kunye ne-adsorbent ye-pole-molekyuli, ngokwe-adsorbed ye-molecular polarization, amandla okuncamathisela anamandla emanzini, i-oxide, i-acetic acid, i-alkali njl. emanzini, akukho kwandiswa, akukho powdery, akukho crack.
