Clay | Definition, Formation, Properties, Uses, & Facts

Clay, soil particles the diameters of which are less than 0.005 millimeter; also a rock that is composed essentially of clay particles. Rock in this sense includes soils, ceramic clays, clay shales, mudstones, glacial clays, and deep-sea clays. Clay materials are plastic when wet and coherent when dry.

Referred to as PM 10 in the USA. Respirable Dust. Particles that will penetrate into the gas exchange region of the lungs. A hazardous particulate size less than 5 microns.

Influence of Bentonite Particles on the Mechanical …

It can be observed that the size of the dispersed bentonite particles ranges from 2 µm to 60 µm in diameter, exposing the size variability that exists in the clay dimension. These characteristics, as has been presented by Fernández et al. [ 26 ] and Ollier et al. [ 27 ], favor the interface between polyester resin and bentonite.

Dustiness behaviour of loose and compacted Bentonite and …

Single-drop and rotating drum dustiness testing was used to investigate the dustiness of loose and compacted montmorillonite (Bentonite) and an organoclay (Nanofil®5), which had been modified from montmorillonite-rich Bentonite. The dustiness was analysed based on filter measurements as well as particle size distributions, the …
