Gibbsite - Wikipedia

Gibbsite, Al(OH) 3, is one of the mineral forms of aluminium hydroxide.It is often designated as γ-Al(OH) 3 (but sometimes as α-Al(OH) 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.. Gibbsite has three named structural polymorphs or polytypes: bayerite

Boehmite - an overview ScienceDirect Topics

Gibbsite is the most common Al oxide mineral. It is often found in highly weathered soils such as Oxisols in tropical areas and in Ultisols. The structure of gibbsite is shown in Fig. 2.6 (Hsu, 1989). There are two planes of closely packed OH − ions with Al 3+ ions between the planes. The Al 3+ atoms are found in two of the three octahedral positions (dioctahedral) and are in hexagonal rings.
