aluminium hydroxide CAS NO (21645-51-2)-Molbase

Description

Aluminium hydroxide, Al(OH)3, is found in nature as the mineral gibbsite (also known as hydrargillite) and its three much rarer polymorphs: bayerite, doyleite and nordstrandite. Closely related are aluminium oxide hydroxide, AlO(OH), and aluminium oxide (or alumina), Al2O3. These compounds together are the major components of the aluminium ore bauxite.
