Physical properties and applications of calcium based bentonite
Physical properties and applications of calcium based bentonite
The main difference between calcium based bentonite and sodium based bentonite is the interlayer cation. The interlayer cation of calcium based bentonite is Ca2. Below, I will introduce its physical properties and applications.
The physical properties of calcium based bentonite are that it is a white or gray white powder, insoluble in water, organic solvents, and oil, and has a large effective pore volume. Therefore, it has good adsorption capacity and a large adsorption capacity. Calcium based bentonite is non-toxic, has a fast filtration speed, low oil content, and good thermal stability.
Calcium based bentonite is used as a binder, decolorizer, adsorbent, catalyst, thickener, thixotropic agent, etc. in industries such as chemical, metallurgical pellets, casting, drilling, etc. It is used as a binder in asbestos insulation, and calcium based bentonite is used as an absorbent in radioactive waste.

Activated clay is an adsorbent made from clay (mainly bentonite) as raw material, which is subjected to inorganic acidification treatment, followed by water rinsing and drying. Its appearance is milky white powder, odorless, tasteless, and has strong adsorption performance. It can adsorb colored and organic substances.
