| Clay is a natural mineral of the smectite family of phyllosilicate group shaped crystals with a layered structure. |
| It is a type of phyllosilicate, exhibiting a two-dimensional sheet or layer structure. |
| Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure. |
| Bleach activator granules consisting of one or more ammonium nitriles and phyllosilicate, obtained by mixing the two components, compressing them and comminuting the resulting agglomerates to the desired particle size. |
| Higher magnification revealed sharp-edged phyllosilicate mineral plates common in schist, apparent in samples of prolonged weathering exposure. |
| Montmorillonite is a very soft phyllosilicate group of minerals that typically form in microscopic crystals, forming a clay. |
