Boehmite, white and relatively soft basic aluminum oxide [AlO(OH)] that is a common mineral in bauxite, in which it forms disseminated grains or pealike masses. It is especially abundant in European bauxites, sometimes as the main constituent; bauxites from the Western Hemisphere commonly contain only a few percent boehmite.
