- noun A white, pearly hydrous aluminum oxide, AlO(OH), found in bauxite, corundum, and dolomite and used as a refractory and abrasive.
from The Century Dictionary.
- noun A hydrate of aluminium occurring in crystals and foliated masses, colorless or of a pearly gray. It is infusible, and a small fragment placed in the flame of a candle, or exposed to the flame of the blowpipe, almost instantly decrepitates and is dispersed: hence its name.

The principal minerals from which aluminum is recovered today are hydrous aluminum oxides, the most prominent of which are bauxite, gibbsite, and diaspore -- the aggregate of all these minerals going commercially under the name of bauxite.

It consists largely of the minerals gibbsite Al (OH) 3, boehmite γ-AlO (OH), and diaspore α-AlO (OH), together with the iron oxides goethite and hematite, the clay mineral kaolinite and small amounts of anatase TiO2.

When I started my PhD project on tree recruitment in French Guiana in 1984, I decided to focus on several key timber species that illustrate a diversity of modes of seed dispersal, from the least to the most efficient in term of distances of dispersal of propagules away from the parent trees, dispersal effectiveness being often dependent on seed size, the smallest diaspore being dispersed the farther.
