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.

List of related compounds and minerals

The aluminium oxides, oxide hydroxides, and hydroxides can be summarized as follows:

aluminium oxides
- corundum (Al₂O₃)
aluminium oxide hydroxides
- diaspore (α-AlO(OH))
- boehmite or böhmite (γ-AlO(OH))
- akdalaite (5Al₂O₃·H₂O) (once believed to be 4Al₂O₃·H₂O), also called tohdite
aluminium hydroxides
- gibbsite (often designated as γ-Al(OH)₃, but sometimes as α-Al(OH)₃,[2] sometimes called hydrargillite or hydrargyllite)
- bayerite (designated often as α-Al(OH)₃ but sometimes as β-Al(OH)₃)
- doyleite
- nordstrandite
