Jun 25, 2018 · Calcium Vs Sodium Bentonite. Either form may be used to clarify a wine, however, the difference between the two are the minerals that get left behind. Sodium bentonite, as the name implies, has sodium (salt) in it. After adding it to a wine it will clear what it can clear and settle out.
Calcium bentonite may be converted to sodium bentonite (termed sodium beneficiation or sodium activation) to exhibit many of sodium bentonite's properties by an ion exchange process. In common usage, this means adding 5–10% of a soluble sodium salt such as sodium carbonate to wet bentonite.

Jul 07, 2021 · Sodium Activation of the Purified Bentonite. The purified bentonite (PB) was prepared for sodium activation: 17 g ± g of the purified sample was weighed into a flask and 250 mL of m NaCl (Puriss) was added. The resulting suspension was stirred at room temperature for 48 h.
Bentonite is a clay generated frequently from the alteration of volcanic ash, consisting predominantly of smectite minerals, usually montmorillonite. Bentonite deposits are normally exploited by quarrying. Extracted bentonite is distinctly solid, even with a moisture content of approximately 30%. The material is initially crushed and, if ...

The two most common types of bentonite clay are calcium bentonite and sodium bentonite. Sodium bentonite is generally mined for industrial uses and is usually not a good choice to take internally. Like all forms of bentonite clay, it expands when it absorbs liquid, but sodium bentonite can absorb much more than any other type of bentonite clay.
