Natural clay mineral for binding, rheology, and adsorption
Bentonite is a natural raw material consisting mainly of smectite group clay minerals. Its interaction with water, swelling behavior, binding strength, adsorption capacity, and rheological effect are important performance criteria depending on the application area. Not every bentonite grade is suitable for every application; product selection must be made according to the mineralogical structure and process conditions.
Key Features
- Controlled interaction with water
- Swelling and gel-forming potential
- Binding and agglomeration support
- Adsorption and rheology function
- Suitability for different industrial activation options
Application Areas
- Foundry sand systems
- Drilling fluids
- Sealing and geotechnical applications
- Iron ore and other pelletization processes
- Adsorbent and carrier systems
Parameters to Consider in Product Selection
- Montmorillonite content
- Swelling and gel strength
- Cation exchange capacity
- Moisture
- Particle size
- Application-dependent rheology and binding performance
BT-1 White Bentonite
BT-1 is a natural white bentonite of Turkish origin, selected for ceramics and other industrial formulations where high montmorillonite content, binding capacity, plasticity, suspension stability, and controlled firing color properties are required together.
The product can be supplied as natural lump material or in processed and ground grades depending on customer requirements.

TECHNICAL NOTE
The performance of bentonite depends on the recipe used and process conditions. The usage rate, grinding fineness, water demand, additives, rheology, and firing curve can directly affect final performance.
It is recommended to conduct trials in the customer's laboratory and, if possible, on an industrial scale before determining the final product specification.
