Clay is that size fraction of the soil that consists of particles of less than 2 μm equivalent spherical diameter. The minerals that usually predominate in the clay fraction are termed clay minerals or phyllosilicates (see Clay minerals: silicates).Clay minerals are hydrous silicates or aluminosilicates, generally secondary, and they commonly form …
2.3.Research methods of interaction between CO 2 and clay minerals. When CO 2 is in direct contact with clay minerals, adsorption occurs due to the special structure of clay minerals. The adsorption of CO 2 on the surface of clay materials is usually studied by both experiments [42, 43] and molecular simulation [44, 45].Clay minerals are mostly …

In addition, some authigenic clay minerals are included in the so-named "special clays" forming bentonite, kerolite-Mg smectite, sepiolite and palygorskite deposits, which are economically relevant …
Kaolinite was the dominant clay mineral in the kaolin deposits and occurrences in Africa with smectite and illite in major quantities, as well as a number of non-clay minerals commonly present in kaolins. Major applications of the kaolins included ceramics, bricks, earthenware, coating, paint, and functional filler.
The small size and their distinctive crystal structure make clay minerals very special with their unique properties including high cation exchange capacity, swelling …

Clay minerals such as kaolinite, smectite, chlorite, micas are main components of raw materials of clay and formed in presence of water. A large number of clays used to form the different structure which …
The clay minerals are of clay-grade phyllosilicates, phyllosilicate minerals whose natural occurrence is confined to the clay-size particle fraction. Clay minerals share another …
Clay minerals are susceptible to alteration during transportation and accumulation in varying environments. This paper investigated the clay mineralogy of sediments in core from Satopanth Tal in the Garhwal Himalaya using XRD method. The clay mineral assemblages in all samples are dominated by Illite (approximately 94%) with …
Therefore, the present Special Issue entitled "Water Pollution Control Using Clay Minerals and Agricultural Biomass-Based Adsorbents" aims at the publication of original research or review papers on the removal of inorganic/organic pollutants from water using various non-conventional, alternative, cost-effective adsorbents derived from ...
Dear Colleagues, We are pleased to announce the launch of a new a Special Issue of the journal Minerals that shall present a set of themed articles on "Clay Mineral Transformations after Bentonite/Clayrocks and Heater/Water interactions from Lab and Large-Scale Tests". The main focus will be on geochemical and mineralogical processes …
This Special Issue encompasses all areas of clay-based materials, including their applications in engineering, nanomaterials, soil, mineralogy, drug delivery, agriculture, biology, medicine, biotechnology, pharmacology, adsorption, photocatalysis, pigments, plastics, cosmetics, and solar cells. This Special Issue welcomes studies on recent ...
The Clay Minerals Society published a complete characterization scheme for its 'Source Clays' but not for its 'Special Clays'. To address this issue, the specific surface areas (SSAs) of the 16 special clays from The Clay Minerals Society were determined using the Brunauer, Emmett and Teller (BET) method of adsorption of an inert gas. Two …
Minerals will publish a Special Issue entitled ''The Universal Application of Clay Minerals''. Clay minerals are ubiquitous on the Earth's surface and their applications date back to the beginning of humanity. They cover a very wide range of topics including industries engineering, the pharmaceutical industry, the adsorption of a wide ...

Minerals runs special issues to create collections of papers on specific topics. The aim is to build a community of authors and readers to discuss the latest research and develop new ideas and research directions. Special Issues are led by Guest Editors who are experts in the subject and oversee the editorial process for papers.
In general, clay minerals are promising substrates for hybrid pigments due to the nanostructures, ion exchange, surface charge, pores of different scales, and multiple active groups. It is believed that clay-based hybrid pigments will play an important role in the pigment industry. This Special Issue is organized into three sections:
Special Issue Information. Dear Colleague, Clays have interesting properties for important environmental applications by acting as sorbents, cation exchangers or flocculants. Accordingly, clays can be used in liners for waste disposal (included radioactive waste) and water purification. The advantages are that these natural materials are often ...
