Bentonite is made from weak bond of alumina and silica sheets that could be divided into thickness of 0.003 micrometers and 0.01 micrometers length in the aquatic environment. The electrostatic charge and easy dividing causes the wide spread in the water.
Bentonite have Na+Ca2 or +Mg2 exchangeable cations and the most ion-exchange capacity in the minerals except Zeolite. This feature affects on bentonite’s commercial properties and classified on this base. Sodium bentonite has high swelling ability and calcium bentonite has low swelling ability. Another basic different between these two minerals is that the sodium one is stable up to 752 Fahrenheit. Calcium bentonite reacts with sodium carbonate to increase its swelling property.
ZaminKav corp. with years of experience as an authority of bentonite production in Iran honored to produce the high quality of sodium and calcium bentonite.
