Meta-kaolin is a chemical phase that forms upon thermal treatment of kaolinite. Kaolinite's chemical composition is Al2O3:2SiO2. 2H2O and as a result of thermal treatment in the range of 400–500 °C, the water is driven away to form an amorphous alumino-silicate called meta-kaolin.
Spe- cial process methods for obtaining a high value added kaolin with process techniques such as "delamination" and "calcination" have been discussed. In order to meet the diverse and growing applications of kaolin to various industries such as paper, ceramics, plastics, rubber and paint both as filler and extender, product specifications …

Removing of peaks related to kaolin at 2θ=12°, 36° after the calcination process, and the formation of meta-kaolin indicates the destruction of the kaolin network. Since the calcination process ...
The metakaolin was produced by thermal treatment (calcination) of the starting high-quality kaolin clay from Serbia. The optimal calcination parameters, for which nearly complete dehydroxylation ...
The applicable process of synthesizing multiple zeolites from kaolin for nucleation, octahedron formation and generation of various types zeolite illustrates in Fig. 4, two steps can be used to expound the synthesis process: (i) Metakaolinization-which involves the transformation of kaolin to metakaolin.

Metakaolin (MK) is created by the calcination of kaolin (firing process) to increase its reactivity/pozzolanicity by increasing the amorphousity nature that plays an …
This aggregation process is very pronounced for kaolin BAL-CO and less intense for kaolin CAO110. Whereas the former is the finest and the latter is the coarsest, we can assume that the intensity of the aggregation process is inversely proportional to the average size of the raw kaolin. ... CAO110 gives meta-kaolin with the lowest specific ...
Geopolymer binders can be made by combining alkali activators with precursor materials including high purity dehydroxylated kaolin (metakaolin) or pulverised fuel ash.

Kaolin is the deposit of naturally occurring minerals containing hydrated aluminum silicates. Widely known as white clay or china clay, these minerals have desirable properties crucial for industrial and commercial applications.For that reason, the kaolin mining and processing steps thoroughly put the nature of the crude deposits and the end …
However, the strength of laterite adding with lime, especially lime and meat-kaolinite mixture, would increase with approaching to dry status, even if which has a slight reduction during drying process. This proved that meta-kaolin and lime were able to inhibit the shrinkage effect of laterite, and increase their overall strength.
