• Other Experimental: Resists high temperatures & may be sterilized by heat;Lamellar aluminum silicate, each lattice layer is sheet of hydrated alumina sandwiched between 2 silica sheets;Very fine powder free from grit, nearly white but may be pale buff or cream color; insoluble in water or acids; odorless with slightly earthy taste; it does not swell in organic solvents /Bentonite USP/;Feels greasy and soap-like ... has a high cation exchange capacity;Interstitial water held in the clay mineral lattice is an additional major factor controlling the plastic, bonding, compaction, suspension and other properties of montmorillonite-group clay minerals;The property of forming gels is very much increased by addition of small amt of alkaline substances such as magnesium oxide.;It has the property of forming highly viscous suspensions or gels with not less than ten times its weight of water.;Forms colloidal suspension in water with strongly thixotropic properties. There are two varieties: (1) sodium bentonite (Wyoming or western), has high swelling capacity in water, and (2) calcium bentonite (southern), with negligible swelling capacity.;The high-swelling Wyoming or sodium bentonites contain ca 30% moisture when delivered to the plant. The Southern or calcium bentonites have ca 25% moisture. The processed bentonite generally contains only 7-8% moisture, although because bentonite is hygroscopic, it may contain considerably more moisture when used.;Bentonites in which sodium montmorillonites are the major mineral constituent have a high swelling capacity.;Bentonites in which calcium montmorillonites are the major mineral constituent commonly have a low swelling capacity. The clays are commonly referred to as Southern or subbentonites.
