Activated calcium bentonite is the most widely used bentonite in winemaking as it has a high swelling index and a pH of between 9 and 10. It also has a high proportion of exchangeable sodium and calcium. It is obtained by activating natural calcium bentonite with sodium carbonate, and then drying and grinding the resulting mixture.

A highly reactive expansive clay utilised in this study is a commercially available sodium activated bentonite. The bentonite has been milled and air classified to give a consistent fine powder. Table 1 provides the chemical analysis of the utilised bentonite which was supplied by Potclays Ltd., UK. The data illustrated that almost 94% …

Ca-bentonites are usually activated with soda using varying proportions of soda. Alkali or soda activation with sodium carbonate (Na 2 CO 3) converts the calcium and/or magnesium bentonites into sodium–calcium forms. In this process which was first proposed by Hofmann and Endell (1936), bentonite moisturized to 35–40% (m/m) is …

Following the activation process, the basic technological characteristics of activated products were analysed, and the results are illustrated in Fig. 2. As seen from Fig. 2A–C that the SI, V, and FL characteristics of 0.5% the soda activated sodium bentonite depend on the ageing time for each bentonite moisture.

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 ...
