Bentonite is a platy clay consisting of the mineral montmorillonite (picture attached). There are two major types of bentonites: Caclium bentonite (non swelling) and Sodium Bentonite (swelling). Montmorillonite have very fine particle size and are highly plastic, strong binders, and exceptional rheological modifiers.

Bentonites are used in ceramics, foundry, iron ore pelletization, cosmetics, etc.

Zigma International currently offers bentonite for three applications:

1. Ceramic Bentonite (ZIGBEN)
2. Foundry Bentonite
3. Iron Ore Pelletization Bentonite

Ceramic Bentonite (ZIGBEN)

Ceramic Bentonite (ZIGBEN) Ceramic Bentonite (ZIGBEN)Ask for Price

Ceramic Bentonite (ZIGBEN) provides plasticity and binding properties without compromising whiteness. This bentonite is imported from Turkey and improves MOR values of ceramic formulations.

Three grades - AL, AO, AA grades

  • White firing bentonite: Bentonite provides plasticity and binding properties without compromising whiteness of fired bodies
  • High water of plasticity: Bentonites exhibit high plasticity which improves workability and dry strength
  • High MOR: Bentonite binds particles in ceramic bodies making them stronger in green or dry state
  • Improved suspension: Bentonite keeps glaze materials suspended
