Smectites, more commonly called bentonite, are candidate as buffer and backfill materials to fill the space around high-level radioactive waste in deep geological repositories. Smectites also serve as additive in paints or as thickening agent for various preparations. ^ CNRLT (2012).

Smectite and vermiculite minerals are often referred to as "swelling" or "expandable" clay minerals. Smectite is commonly a primary constituent of bentonite (see bentonite for respective genesis information) and pelitic sediments (e.g., shales) and occurs in soils.

May 1, 2023 · Smectite minerals are a group of phyllosilicate minerals that are characterized by a layered structure and the ability to swell when exposed to water. The mineral group includes a variety of species, including montmorillonite, nontronite, saponite, and hectorite.

Smectite is the main clay mineral constituent in all studied samples (Table 6). It ranges between 48.8% (Section 1, east station, sample No. 1) and 52% (Section 2, Tongara, sample No. 9).

The physicochemical properties of smectite clay minerals that determine their industrial utilization are reviewed. Smectite is the name used for a group of phyllosilicate mineral species, the most important of which are montmorillonite, beidellite, nontronite, saponite and hectorite.

Jan 1, 2013 · Smectites consist of plate-like particles often displaying cloudy or crumble morphology with folded edges. The lateral dimension of smectite particles could be much larger than 2 μm, while the thickness of the particles (height of stacks) could be much smaller.

Smectite crystals are phyllosilicates with a 2:1 structure composed by stacking several layers of one octahedral sheet between two tetrahedral ones.

…clay minerals belonging to the smectite group, which are hydrous aluminum silicates containing iron and magnesium as well as either sodium or calcium. Two types of bentonite are recognized, and the uses of each depend on specific physical properties.

Mar 1, 2019 · Smectite is proposed to reduce gut inflammation, reduce toxin penetration by acting as a barrier, and increase water absorption. 1 This Cochrane review included 18 trials with 2,616 children.

Jan 1, 2013 · Smectite, also known as “swelling clay”, is a diverse group of clay minerals with a 2:1 layer silicate structure that can expand and contract upon wetting and drying. All 2:1 layer silicates (which also include illite/mica, chlorite, and vermiculite groups) have 2 tetrahedral sheets surrounding a central octahedral sheet.
