Use in drilling muds

Drilling muds consist of water to which sodium bentonite and pulverized barytes are added. Such muds are prepared mainly for deep drilling, like oil-well drilling. Bentonite imparts two properties:

  • It gives the fluid a viscosity several times that of water and thixotrophy.
  • It seals the wall of the holes, thus preventing water loss.

The quantity of bentonite used is variable depending upon the depth of the hole to be drilled.


Betonit for foundry

Bentonite is used in foundry to bind the sand grains into desired shapes. Bentonite helps in retaining the mechanical shape of the mould by making the particles of sands adhere and also making the surface impermeable. Strength and fusion point are the two important properties desired for selecting bentonite. Generally, the swelling type of bentonite is used though other types of bentonites have also been used.
