Chemical Properties

Solubility
Insoluble in water and forms a colloidal solution.

Applications

Bentonite, sodium form is used as a suspending agent, a gel binder, a filler in ceramics and a catalyst support.Sodium bentonite is widely utilized as a natural sealant in recreational ponds, dairy and sewage lagoons and city landfills. Due to its colloidal property, it is employed in drilling mud for oil and gas wells. Due to its swelling property, it provides a self-sealing low permeability barrier. It combines with polymers and enhances the surface modifications, which are used for rheological or sealing performance in geo-environmental applications.

Notes

Forms a colloidal suspension in water.
