Bentonite
- CAS Number: 1302-78-9
- (Na₀.₃₃(Al,Mg)₂Si₄O₁₀(OH)₂·nH₂O)
Description
Uses and Applications
Its water absorption capacity and colloidal properties make it a widely used raw material in the ceramic industry. It provides stabilising and thickening properties in ceramic bodies, engobes and glazes, as well as in detergents and paints. Bentonite is also used in foundation and geotechnical construction applications.
Packaging and Logistics
We supply bentonite in 25 kg bags and big bags, supported by agile logistics to facilitate its integration into processes already validated by our customers.

- Frequently Asked Questions
Frequently Asked Questions About the Bentonite
What is bentonite and which mineral is it made of?
What is bentonite and which mineral is it made of?
Bentonite is a natural clay whose main constituent is montmorillonite, a layered silicate. That layered structure explains its behaviour: it allows water to enter between the layers, which gives rise to its swelling and colloidal properties.
What is bentonite used for in foundry work?
What is bentonite used for in foundry work?
In green sand moulding it acts as a binder: it coats the sand grains and gives them cohesion and plasticity, so that the mould holds its shape during pouring. Its capacity to retain water is what maintains those properties throughout the moulding cycle.
What is the difference between sodium and calcium bentonite?
What is the difference between sodium and calcium bentonite?
The difference lies in the predominant exchangeable cation. Sodium bentonite has a considerably higher swelling capacity, so it is used where viscosity and binding power are required. Calcium bentonite swells less and is aimed at absorption and bleaching applications. It is worth confirming this when defining the application.
