The type of bentonite, the source, and its purity influence its properties. Bentonite is a complex hydrated aluminum silicate with exchangeable cationic components: (Al, Fe, Mg) Si 4 O 10 (OH)2 (Na+,Ca++). The most commonly used form in the United States is sodium bentbnite. Sodium bentonite has enhanced protein binding ability over calcium ...
PD Bentonite LLC. 3260 N Hayden Rd Ste 210 Scottsdale, Az. Exclusive supplier of high purity calcium bentonite. Our bentonite is gently harvested from our remote pristine lands within the Painted Desert Arizona. The unique history and prehistoric state land yields an unmatched matrix quality.
The induced negative layer charge (x) is in the range of 0,4 to 1,2 unit charges per O20(OH)4-unit and is balanced by interlayer cations (c). The octahedral sheet is composed of magnesium and aluminium coordinated octahedrally with oxygen atoms or hydroxyl groups. The silica tetrahedra are interconnected in a silica sheet structure.
Cape Bentonite is a natural material that consists of variable proportions of various minerals, including Montmorillonite, quartz and mica. Cape Bentonite products consist primarily of montmorillonite and other minor natural minerals. Hazardous Ingredient: Approximate Weight %: CAS no: Montmorillonite >90% Quartz <10% 1
Conversely, calcium bentonite, with calcium cation prevalence (Ca2+), while getting hydrated in much the same way, due to its strong positive charge, has lower absorption properties, not permitting water to penetrate through the platelets. In this latter case, platelets flake off rather than swell.
