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.{{Ullmann |doi=10.1002/14356007.a01_557|title=Aluminum Oxide|year=2000|last1=Hudson|first1=L.
