The answer is that both are correct. Kaolinite and montmorillonite are both types of clay minerals that are commonly found in soils. Kaolinite is a type of clay mineral that is composed of aluminum, silicon, and oxygen. Montmorillonite, on the other hand, is a type of clay mineral that is composed of aluminum, magnesium, silicon, and oxygen.
Nous avons souvent tendance à classer les argiles selon leurs couleurs. Leurs compositions (illite, kaolin ou montmorillonite) sont bien plus parlantes.
Raw clays containing kaolinite (kaolin) are promising substitute materials. In the field, raw clays are often mixed with calcite and this is thought to affect their behaviour after calcination. ... which leads to a slight difference in the calculated convective used in the derivation of Eq.

kaolinite, group of common clay minerals that are hydrous aluminum silicates; they comprise the principal ingredients of kaolin (china clay). The group includes kaolinite and its rarer forms, dickite and nacrite, halloysite, and allophane, which are chemically similar to kaolinite but amorphous. Kaolinite, nacrite, and dickite occur as minute ...
The dried raw sludge (DS100) presented kaolinite (Al 2 (Si 2 O 5)(OH) 4), which is a mineral commonly found in clays and provides a good indication that the sludge can change into a pozzolan after calcination, owing to the transformation of kaolinite into amorphous material. The percentages of the phases identified using Rietveld refinement ...

In this regard, kaolinite (Kaol) is one of the well-known abundant and low-cost natural clays, which is available worldwide in rocks as crystalline structure. The chemical composition of Kaol was 39.5% Al 2 O 3, 46.5% SiO 2 and 14.0% H 2 O (by mass%) (Sternik et al., 2020). It is layered with two different interlayer surfaces.
The elemental compositions of the Kaol and ATKaolCat samples are shown in Table 1 while the EDX spectra are shown in Fig. 2.The percentage of both Al and Fe reduced in ATKaol while Si and O 2 increased, the reduction in Al and Fe, and the increment in Si were due to the leaching effect of the phosphoric acid (Panda et al., 2010).The …
In this work, nanocomposite hydrogels on the basis of polyvinyl alcohol and mineral kaolinite clay were prepared via freezing–thawing cyclic method without using any chemical crosslinkers as well as any intercalants for modification of kaolinite. The nanocomposite hydrogels were characterized by XRD, TEM, SEM, and FTIR methods.

The feedback between CO 2 sources and sinks through chemical weathering is one of the important reasons why Earth has maintained a habitable climate for over four billion years. The lithium (Li) isotopic system is a promising tracer of silicate weathering, but the mechanisms causing its isotope fractionation during weathering remain ambiguous.
Specimen # 222164.
