Montmorillonite, a phyllosilicate, is a soft type of mineral that exists in small crystals which accumulate to form clay. Phyllosilicates or sheet silicates, are a group of minerals that include the micas, chlorite, serpentine, talc, and the clay minerals. The clay is named after Montmorillon (France) where it was first discovered.
There exist two types of montmorillonite, sodium and calcium. Sodium montmorillonite is commonly known as sodium bentonite. The presence of sodium as the predominant exchangeable cation can result in the clay swelling to many times its original volume. Sodium montmorillonite has most of its uses in the industries whereby it is used in : oil well drilling mud, plaster, cat litter, cement tiles, lubricating grease, dynamite, matches, paints, copy paper, shoe polish, concrete, cleaning agents, wall boards, and crayons. Most of these uses are attributed to swelling property of sodium montmorillonite.
Calcium montmorillonite, is also known as “living clay”. Why is it called living clay? It is called so because it majorly consists of minerals that improve the production of enzymes in living organisms.
