Descrizione generale
Aluminum oxide (Alumina, Al2O3) is commonly used as adsorbent. Formation of protective α-Al2O3 scales on the alloys at high temperatures has been studied.[1] Polycrystalline Al2O3 has been employed to investigate the self-diffusion coefficient of aluminum in the temperature range of 1670°-1905°C.[2] Aluminium oxide can either be obtained via thermal conversion of aluminium hydroxide at temperatures >1200οC or via combustion of aluminium.[3] Aluminium oxide nanoparticles can behave like safe adjuvants and carriers for eliciting antibodies from small molecules called haptens.[4]
Applicazioni
Aluminum oxide (Alumina) may be employed for the selective adsorption of the catecholamines during their determination in diverse biological matrices.[5] It may be used in the fabrication of polycrystalline lithium iodide - aluminum oxide solid electrolytes. The incorporation of aluminum oxide remarkably increased the conductivity of lithium iodide.[6] Aluminum oxide (activity II-III, according to the Brockmann scale) has been used for the chromatographic purifications.[2]
