Nghĩa của từ gibbsite bằng Tiếng Anh
The remaining clay component from the limestone can be further altered by these acids and, over time, it is converted to aluminium oxyhydroxide minerals such as gibbsite , diaspore, and boehmite.

1. Boehmite produced fibrous Boehmite particles within the amorphous matrix of the decomposed gibbsite particles, which exhibited a poorly crystalline structure and smaller size than the initial gibbsite particles
2. Gibbsite has a typical metal hydroxide structure with hydrogen bonds.
3. Gibbsite is named after George Gibbs (1776–1833), an American mineral collector.
4. Gibbsite, Al(OH)3, is one of the mineral forms of aluminium hydroxide.
5. It is actually a rock composed of aluminum hydroxides of mostly Bohmite, Gibbsite and Diaspore
6. 28 Thermal analysis implies that the bauxite samples are of 2 obvious endothermic peaks, which are gibbsite and diaspore endothermic peak.
7. Aluminium hydroxide (gibbsite) can be dissolved in 20–25% aqueous NaOH solution at a temperature near the boiling point.
8. Aluminium hydroxide (Aluminic), found in nature as the mineral gibbsite, is amphoteric (i.e., it has both basic and acidic properties)
9. Boehmite (γ-AlOOH) and gibbsite (α-Al (OH) 3) are important archetype (oxy)hydroxides of aluminum in nature that also play diverse roles across a plethora of industrial applications.
10. A further study on the effect of gibbsite particle size on its agglomeration kinetics is in order, since previous studies tell us different results.
11. ‘The spacing between the protruding oxygen atoms is comparable to the spacing between certain of the hydroxyl groups in layers of magnesium hydroxide (Brucite) or aluminum hydroxide (gibbsite).’
12. A Boehmite is obtainable by the hydrothermal treatment of an aqueous slurry of a Boehmite-forming compound such as gibbsite, and has a characteristic crystal form
13. Coarse gibbsite particles, obtained from the Bayer Process, are lightly calcined and the non-Boehmite-containing material is removed by dissolution in caustic aluminate liquors of appropriate composition.
14. Bauxites are residually enriched rocks, mostly composed of Al-hydroxides (gibbsite, boehmite and diaspore), kaolinite, Fe-oxy-hydroxides and Ti-oxides, which form from intense lateritic weathering of aluminosilicate protoliths
15. The influence of the starting materials as sources of aluminum, amorphous aluminum hydroxides, pseudoboehmite, allophane or gibbsite, has also been examined by X-ray diffraction, scanning electron microscopy, and by energy dispersive analysis.
16. The principal minerals in Bauxite are gibbsite (Al 2 O 3.3H 2 O), boehmite (Al 2 O 3.H 2 O) and diaspore, which has the same composition as boehmite, but is denser and harder.
17. Bauxite is not a mineral, but rather a group of aluminum oxide s. The term is generally used to describe the economically important mixture of these minerals, which form a mass of the individually classified members of Gibbsite, Boehmite, and Diaspore.
18. In this study, which is a first attempt toward that objective, the texture of kaolin produced by four different variations of hydrothermal synthesis using amorphous silica, allophane, and gibbsite in H2SO4 and H4EDTA solutions are illustrated with SEMs.

20. They are very diverse: from rendzina soils to red soils (Rotlehm); from silt to pure clay; from siallitic (high silica content) residues to allitic (very low silica content) formations; from clays rich in kandite-minerals (kaolinite, halloysite) to bauxites containing gibbsite boehmite.
