Bentonite powder is a natural clay made mostly of sodium montmorillonite. This is a drilling grade that the record lists as meeting API 13A.
In water-based drilling muds it builds viscosity, carries cuttings out of the hole, forms a thin filter cake to control fluid loss and helps keep the borehole stable. It is also used in piling and diaphragm-wall slurries, earthing (grounding) backfill, foundry sand binders and as a sealing clay.
We keep stock at our Barka warehouse and deliver across Oman, including Muscat, Sohar, Salalah and Duqm. Send the quantity and pack size you need and we will quote.
Bentonite, also called montmorillonite clay, is built from layers about 10 angstroms thick, each made of two tetrahedral sheets and one octahedral sheet. This structure gives it three useful properties: it absorbs large amounts of water, it exchanges ions, and it forms thixotropic gels.
