Alumina is obtained as a white amorphous powder by heating aluminiumhydroxide.

Adsorption of the Hib-TT onto aluminiumhydroxide resulted in higher levels and an earlier Hib antibody response in infant rhesus.

Amorphous substances, such as ferric hydroxide, aluminiumhydroxide, or silicic acid, separate in a gelatinous form and are relatively difficult to filter and wash.

When first precipitated the hydroxides are all readily soluble in acids, but aluminiumhydroxide dissolves with considerable difficulty after standing or boiling for some time.
