Bentonite Manufacturers in India
Bentonite clay reacts with water, capturing it in the leaves that form the bentonite structure, allowing control of rheology in ceramic slurries. As trusted bentonite manufacturers in India, Expolica Ceramics supplies high-quality material for diverse applications. A small amount of bentonite added to clay can increase its plasticity, hence easing forming of articles by some shaping techniques.
- Exceptional Workability
- Enhanced Green Strength
- Rheology Control
- Powerful Swelling Capacity
Why Choose expolica as,
Bentonite Clay Suppliers
Expolica Ceramics extracts premium bentonite clay from specialized deposits across our five mines. As experienced bentonite exporters in India, we deliver high-swelling sodium bentonite with exceptional plasticity for ceramic slip preparation, glazing, and body formulation applications.
- High Swelling Index: Our sodium bentonite achieves swelling indices between 24-30 ml/2g, significantly higher than calcium bentonite varieties. This exceptional swelling capacity means you need smaller additions (2-4%) to achieve desired plasticity and suspension properties.
- Controlled Cation Capacity: With CEC values ranging from 80-100 meq/100g, our bentonite provides optimal interparticle attraction for green strength enhancement. This controlled exchange capacity prevents excessive water absorption that causes processing difficulties.
- Fine Particle Distribution: We process bentonite to achieve 95% passing through 200 mesh screens, ensuring uniform dispersion throughout ceramic slips and glazes. Fine particles activate quickly upon water contact, reducing mixing time and energy requirements.
- Rheology Modifier: Our bentonite transforms water-clay systems into thixotropic fluids ideal for slip casting operations. It maintains suspension stability preventing settling during storage, yet allows controlled pouring into molds.
- Minimal Grit : Through careful mining from pure bentonite seams and screening processes, grit content remains below 2% and organic matter under 0.5%. Clean bentonite prevents surface defects, pinholes, and discoloration in fired products.
- Moisture-Controlled: Available in moisture-sealed 25kg bags, 50kg bags, or bulk shipments based on storage capabilities. Properly packaged bentonite maintains consistent moisture content (8-12%), ensuring predictable performance without pre-drying requirements.
