Bentonite
Al₂O₃·4SiO₂·nH₂O
Swelling smectite clay supplied for ceramics, foundry, drilling, and industrial binding applications.
Overview
Bentonite is a smectite-group clay mineral with exceptional swelling, binding, and rheological properties. It is used in ceramics as a plasticizer and binder, in foundry as a green sand binder, and in civil engineering and drilling as a sealant and viscosifier. Montmorillonite content governs its swelling index and commercial suitability.
