Silica-alumina hydrates (SIRAL) and the corresponding oxides (SIRALOX) exhibit characteristics which differ significantly from pure aluminas. One of the key properties of silica-aluminas is their comparatively high level of surface acidity, making them useful catalyst support materials, for example in the field of refinery catalyst or in diesel-engine applications.
