Bentonite is a naturally occurring clay composed primarily of montmorillonite , a layered alumino-silicate mineral known for its exceptional swelling, absorbency, and binding characteristics . When hydrated, bentonite forms a thixotropic gel , making it an essential functional material across a wide range of industrial applications.
Due to its rheological control , sealing ability, and chemical stability , bentonite is widely used in drilling fluids, foundry molding sands, iron ore pelletizing, civil engineering, and environmental protection systems . Its natural origin and cost-effectiveness further enhance its value in demanding industrial processes.
