Clay mineral

Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces.. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them. They are important constituents of soils, and have been useful to humans. Clay minerals are the function minerals of the earths close to floor environments. They shape in soils and sediments, and through diagenetic and hydrothermal alteration of rocks. Water is essential for clay mineral formation and most clay minerals are defined as hydrous alumino silicates Clay minerals in drilling fluids: functions and challenges. A novel method for solving the impact of clay on concrete workability: dimensional design and mechanism analysis. Thermal degradation kinetics of sepiolite.

Clay Minerals is an international journal of mineral sciences, published four times a year, including research papers about clays, clay minerals and related materials, natural or synthetic. The journal includes papers on Earth processes, soil science, geology/mineralogy, chemistry/material science, colloid/surface science, applied science and technology and health/ environment topics ADVERTISEMENTS: This article throws light upon the six main types of clay minerals. The types are: 1. Kaolinite 2. Smectite Group 3. Illite Group 4. Vermiculite 5. Chlorite 6. Allophanes. Type # 1. Kaolinite: The most prominent member of the 1: 1 type of clay minerals is kaolinite, in which one silica tetrahedral layer is [ Definition: Clay minerals are the characteristic minerals of the earths near surface environments. They form in soils and sediments, and by diagenetic and hydrothermal alteration of rocks. Water is essential for clay mineral formation and most clay minerals are described as hydrous alumino silicates

Clay is an abundant, naturally occurring, fine-grained material composed predominantly of hydrous aluminum silicates. Clay is not a single mineral, but a number of minerals. Clays fall into six general categories: kaolin, ball clays, fire clays, bentonite, common clays and Fuller's earth. Clays are common all over the world Clay minerals are also especially affected by ion exchange as they have a strong capacity for exchange within interlayers and with surface ions. During exchange of ions, the basic structure of the clay mineral is unchanged, but the interlayer spacing changes depending on the size of the ions entering interlayer positions Clay minerals have a wide range of particle sizes from 10's of angstroms to millimeters. (An angstrom is a unit of measure at the scale of atoms.) Thus, clays may be composed of mixtures of finer grained clay minerals and clay-sized crystals of other minerals such as quartz, carbonate, and metal oxides

Clay mineral - Clay mineral - Chemical and physical properties: Depending on deficiency in the positive or negative charge balance (locally or overall) of mineral structures, clay minerals are able to adsorb certain cations and anions and retain them around the outside of the structural unit in an exchangeable state, generally without affecting the basic silicate structure Clay minerals, in common with many other fine-grained materials, are used as fillers and functional additives in industries such as paper, polymers, and paints where loading levels can be as high as 60wt.%. Often, the functional particle characteristic is shape Clay minerals typically form over long periods as a result of the gradual chemical weathering of rocks, usually silicate-bearing, by low concentrations of carbonic acid and other diluted solvents.These solvents, usually acidic, migrate through the weathering rock after leaching through upper weathered layers. In addition to the weathering process, some clay minerals are formed through. Clay Minerals, 30, 89-98. Churchman G.J., Pontifex I.R. & McClure S.G.

  1. erals are commonly > 2 μm, or even 4 μm in at least one dimension. Their small size and large ratio of surface area to volume gives clay
  2. erals are generally classified into three layer types based upon the number and arrangement of tetrahedral and octahedral sheets in their basic structure. These are further separated into five groups that differ with respect to their net charge (Table 2). 1:1 Clay Minerals The 1:1 layer
