Common names of clays are used in literature when studying effects in animals. Considering the differences observed between the different montmorillonites, the terms bentonite, smectite, montmorillonite and HSCAS may not describe – at least generally – the same substance. The "bentonite" is a naturally occurring clay soil type, while the "smectite" is a type of clay minerals. The last is the predominated clay mineral in bentonite, however, a wide variety of other Bentonite (dioctahedral montmorillonite) is an additive proposed to be authorised as a substance for the reduction of the contamination of feed by mycotoxins for all animal species at a recommended use level ranging from 0.05 and 0.3 in complete feed. Bentonite Clay is classed as a smectite – swelling clay that has powerful drawing and absorptive properties. There are four types of Bentonite Clay, also referred to as Montmorillonite. They are: sodium; calcium; magnesium; potassium Montmorillonite Chemical Equation: Na 0.2 Ca 0.1 Al 2 Si 4 O 10 (OH) 2 (H2O) 10 " Sodium bentonite is the name for the ore whose major constituent is the clay mineral, sodium montmorillonite.

They are rocklike in nature and usually extracted by opencast mining (quarrying). Natural sodium bentonite as the name suggests occurs with sodium Bentonite is an off-white montmorillonite clay formed from altered volcanic ash. It has a sheet-silicate structure and is especially notable for the way in which it absorbs and loses water and for its base-exchange properties. Sodic bentonite can absorb up to 10 times its own weight in water and can swell to 18 times its dry volume. Bentonite principally consists of sodium montmorillonite in combination with 10 to 20% of various mineral impurities such as feldspars, calcite, silica, gypsum, etc. Sodium montmorillonite clays are the industrial clays used in things like: plaster, oil well drilling mud, cat litter, matches, cement tiles, lubricating grease, paints, copy paper, dynamite, shoe polish, concrete, cleaning agents 2012-04-24 · Comparing Bentonite with Zeolite by Chris van der Walt This article was compiled for a newsletter, distributed to healthcare professionals and resellers of related products.
