Are there any differences between bentonite and kaolin?
Kaolin is a nonmetal mineral, is a kind of clay mineral mainly kaolinite clay and clay rock. Named for Jiangxi province Jingdezhen Gaoling village. The pure kaolin is white and delicate, soft soil, plasticity and fire resistance and other physical and chemical properties. Its good mineral is mainly composed of kaolinite halloysite, hydromica, illite, montmorillonite and quartz, feldspar and other minerals. Kaolin is widely used, mainly used for papermaking, ceramics and refractories, secondly used in coating, rubber filler, enamel glaze and white cement raw materials, a small amount of used plastics, paint, pigment, grinding wheel, pencil, cosmetics, soap, pesticide, medicine, textile, petroleum, chemical industry, building materials, defense and other industrial sectors.
Bentonite (Bentonite) predominantly montmorillonite aqueous clay minerals. The chemical composition of montmorillonite: (Al2, Mg3) Si4O10 OH2 nH2O, because it has special properties such as swelling, adhesion, adsorption, catalysis, thixotropy, suspension and cation exchange. So widely used in various industrial fields.
