Gibbsite, Al (OH) 3, is one of the mineral forms of aluminium hydroxide. It is often designated as γ-Al (OH) 3[2]: 2 (but sometimes as α-Al (OH) 3[3]). It is also sometimes called hydrargillite (or hydrargyllite). Gibbsite is an important ore of aluminium in that it is one of three main phases that make up the rock bauxite.

三水铝石（gibbsite）与 拜三水铝石 （bayerite）和 诺三水铝石 （nordstrandite）成 同质多象 。 旧称 三水铝矿 或 水铝氧石 。 成分Al(OH) 3 ，含Al 2 O 3 65. 4%，常含铁和镓。

2024年9月12日 · Gibbsite is a naturally occurring mineral form of aluminum hydroxide with the chemical formula Al(OH)₃. It belongs to the hydroxides and oxides mineral class and is one of the three main components of bauxite, the primary ore of aluminum. Gibbsite appears as colorless to white or gray crystals, often displaying a pearly luster and typically ...

Gibbsite (Al(OH) 3) has a monoclinic structure (space group P2 1 /n). Gibbsite is most frequently produced by weathering of rocks containing Al-bearing minerals and as such it is a major constituent of laterite and bauxite distributed through the weathering profile and occurring as weathering crusts (Fig. 6 B). It is also formed under very low ...

Gibbs was a wealthy import merchant who was a geologist and mineralogist. He helped found early scientific societies for mineralogy and geology and wrote several scientific articles on geology, mineralogy, and agriculture.

2010年12月15日 · Gibbsite is a starting material for the production of high surface area α-Al 2 O 3 which is widely used in the ceramics industry and as an adsorbent or a catalyst support in the chemical industry. Because of gibbsite surface gibbsite’s differential alkalinities, it has also been used as a substrate for direct treatment of stomach diseases [3] .

Gibbsite is one of the three component minerals of the economically important aluminum ore Bauxite. Gibbsite was first discovered in 1820 by Chester Dewey (1784-1867) of Williams College, Massachusetts. It was first thought to be Wavellite, but a year later it was determined to be a separate mineral species and was subsequently named Hydrargillite.

Polymorphous with bayerite, doyleite, and nordstrandite. Occurrence: A typical product of weathering of aluminous minerals, common in lateritic soils and bauxite. Also formed in low-temperature hydrothermal and metamorphic environments, replacing aluminous minerals. Diaspore, b ̈ohmite, corundum, kaolinite, goethite.

三水铝石（gibbsite） 化学组成为Al(OH)3、晶体属单斜晶系 P21/n空间群的氢氧化物矿物。与拜三水铝石(bayerite)和诺三水铝石 (nordstrandite)成同质多象。旧称三水铝矿或水铝氧石。以矿物收藏家C.G.吉布斯 (Gibbs)的姓于1822年命名。
