Aluminium hydroxide gels can be dehydrated (e.g. using water-miscible non-aqueous solvents like ethanol) to form an amorphous aluminium hydroxide powder, which is readily soluble in acids. Heating converts it to activated aluminas, which are used as desiccants , adsorbent in gas purification, and catalyst supports .
Calvet et al. coined the name pseudoboehmite in 1952 when they synthesized pure aluminium hydroxyde gel. [ 1 ] [ 2 ] Its XRD pattern is similar to that of boehmite but the relative intensities of the peaks differ.
[14] [15] Alum was the first aluminium salt used for this purpose, but has been almost completely replaced by aluminium hydroxide and aluminium phosphate for commercial vaccines. [16] Aluminium salts are the most commonly-used adjuvants in human vaccines. Their adjuvant activity was described in 1926. [17]
Aluminium hydroxide oxide or aluminium oxyhydroxide, AlO(OH) is found as one of two well defined crystalline phases, which are also known as the minerals boehmite and diaspore. The minerals are important constituents of the aluminium ore , bauxite .

The most commonly used adjuvants are aluminium salts such as aluminium hydroxide, aluminium phosphate or potassium aluminium sulphate (also simply called alum). [24] [25] These aluminium salts can be responsible for soreness and redness at the vaccination site but do not cause any long-term harm to human health. The amount of aluminium in these ...
Boehmite or böhmite is an aluminium oxide hydroxide (γ-AlO(OH)) mineral, a component of the aluminium ore bauxite. It is dimorphous with diaspore. It crystallizes in the orthorhombic dipyramidal system and is typically massive in habit. It is white with tints of yellow, green, brown or red due to impurities.
Aluminium hydroxide, Al(OH) 3, aluminium with three hydroxy groups attached, is a complete molecule, so it is not a "basic aluminium" compound. Aluminium acetate is a name for three salts in the solid state: dihydroxyaluminium aluminium acetate, hydroxyaluminium diacetate, and aluminium triacetate, Al(CH 3 CO 2) 3.
