  • 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.

from the GNU version of the Collaborative International Dictionary of English.

  • noun (Min.) A hydrate of alumina, often occurring in white lamellar masses with brilliant pearly luster; -- so named on account of its decrepitating when heated before the blowpipe.

  • 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.
