Bentonite (/ ˈbɛntənaɪt / BEN-tə-nyte) [1][2] is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite. Na-montmorillonite has a considerably greater swelling capacity than Ca-montmorillonite.

皂土（英語： bentonite ），也称膨土、膨润土，是硅酸铝粘土吸收剂，主要由蒙脱石构成。 英文名“ Bentonite ”是1898年由Wilbur C. Knight根据 罗克里弗 的 白垩纪 本顿页岩 （ 英语 ： Benton Shale ） （ Benton Shale ）命名的。

有机膨润土是一种无机矿物/有机铵复合物，以膨润土为原料，利用膨润土中蒙脱石的层片状结构及其能在水或有机溶剂中溶胀分散成胶体级粘粒特性，通过离子交换技术插入有机覆盖剂而制成的。 有机膨润土在各类有机溶剂、油类、液体树脂中能形成凝胶，具有良好的增稠性、触变性、悬浮稳定性、高温稳定性、润滑性、成膜性，耐水性及化学稳定性，在涂料工业中有重要的应用价值。 在油漆油墨、航空、冶金、化纤、石油等工业中也有广泛的应用。 膨润土矿是一种多种用途的 …

膨润土(Bentonite) 按译音,是以蒙脱石为主的含水粘土矿，由于它具有特殊的性质。 如:膨润性、粘结性、吸附性、催化性、触变性、悬浮性以及阳离子交换性等等,所以广泛用于各个工业领域。

膨润土（ Bentonite），又称斑脱岩、膨土岩等，含少量长石、石英、贝得石、方解石及火山碎屑物。 主要化学成分是SiO2、Al2O3及少量Fe2O3、MgO、CaO、K2O、Na2O和TiO2等。

2023年5月2日 · Bentonite is a type of clay that is composed primarily of the mineral montmorillonite. It is a highly absorbent clay that has many uses in various industries, including cosmetics, pharmaceuticals, and construction. One of the most common uses of bentonite is as a drilling fluid in the oil and gas industry.

1978年1月1日 · Bentonites have a variety of uses in various industries. The properties of bentonites are contingent upon the fact that they are composed of smectite clay minerals, and the properties of the smectite in turn are contingent upon its chemical composition, atomic structure, and morphology.

2025年3月5日 · Bentonite, clay formed by the alteration of minute glass particles derived from volcanic ash. It was named for Fort Benton, Mont., near which it was discovered. The formation of bentonite involves the alteration of volcanic glass to clay minerals; this requires hydration (taking up or combination
