BENTONITE

BENTONITE

Bentonite is a naturally occurring clay formed from the weathering of volcanic ash, and it’s primarily composed of the mineral montmorillonite, a type of smectite. It’s valued for its high absorbency, swelling capacity, and cation exchange properties, making it useful in a wide range of industries.

Types of Bentonite

1. Sodium Bentonite

  • Swells significantly when exposed to water (up to 15–20 times its dry volume)
  • Excellent sealing and binding properties
  • Used in drilling muds, sealing ponds and landfills, and foundry sands

2. Calcium Bentonite

  • Lower swelling capacity than sodium bentonite
  • More commonly used in cosmetics, pharmaceuticals, and as an absorbent

3. Potassium Bentonite

  • Rare used in specific industrial processes

Key Properties

Swelling

High capacity to absorb water and expand

Viscosity

Used as a thickener in slurries

Thixotropy

Becomes fluid when agitated and thickens when at rest

Ion exchange capacity

Can absorb and release cations, making it useful for purification

Applications & Uses

imrs

Oil & Gas

Drilling mud for lubrication and cuttings removal

Drilling mud plays a crucial role in oil and gas operations by lubricating the drill bit and efficiently carrying rock cuttings to the surface. It ensures smoother drilling and prevents equipment wear.

Construction

Slurry walls, waterproofing, sealing

In construction, Bentonite forms slurry walls for waterproofing, sealing, and foundation stabilization. It creates a barrier to control groundwater and soil movement.

Molding sand binder in metal casting

Bentonite acts as a sand binder in metal casting molds, providing strength and thermal stability. It ensures smooth mold surfaces and precise casting shapes.

Environmental

Waste containment, landfills, remediation

Used in landfills and waste containment, Bentonite prevents leachate leakage. It aids in soil remediation by immobilizing contaminants.
