Webbentonite, clay formed by the alteration of minute glass particles derived from volcanic ash. It was named for Fort Benton, Mont., near which it was discovered. The formation of bentonite involves the alteration of volcanic glass to clay minerals; this requires hydration (taking up or combination with water) and a loss of alkalies, bases, and possibly silica, … WebThe results showed that the Ca bentonites produced a significantly smaller colloid fraction compared to the Na bentonites (e.g., Ca-MX80 53 ± 7 ppm, Na-MX80 600 ± 50 ppm), and that whilst the Na and Na-Ca mixed clays showed a positive relationship between colloid formation and starting smectite content, the Ca clays colloid formation was invariant with …
