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. Aluminium hydroxide is amphoteric, i.e., it has both basic and acidic properties. Closely related are aluminium oxide hydroxide, AlO(OH), and aluminium oxide or alumina (Al2O3), the latter of which is also amphoteric.

WebOct 15, 2024 · The U.S. Department of Energy's Office of Scientific and Technical Information Gibbsite, Al(OH)3, is one of the mineral forms of aluminium hydroxide. It is often designated as γ-Al(OH)3 (but sometimes as α-Al(OH)3. ). It is also sometimes called hydrargillite (or hydrargyllite). Gibbsite is an important ore of aluminium in that it is one of three main phases that make up the rock bauxite. streptomyces griseus biochemical tests
