1. Product Description
Aluminium hydroxide, Al(OH)3, is found as the mineral gibbsite (also known as hydrargillite) and its three much rarer polymorphs: bayerite, doyleite, and nordstrandite. Aluminium hydroxide is amphoteric, i.e., it has both basic and acidic properties. Closely related are aluminum oxide hydroxide AlO(OH), and aluminum oxide or alumina (Al2O3), the latter of which is also amphoteric. These compounds together are the major components of the aluminum ore bauxite. Aluminium hydroxide also forms a gelatinous precipitate in water.
