Sedimentation ceramic suspensions

Therefore the sedimentation velocity of a ceramic suspension with a hi volume fraction is less than that of a sin e particle.

Bentonite Number. A measure of sedimentation resistance, expressed in terms of the heights of clear and turbid portions of the liquid column, and its overall density. A sharp boundary between the suspension and the clear liquid is formed by adding bentonite. (Glass Ceram. 39 (5) 224 1983). 

The changes in density of a sedimenting suspension may be followed with a hydrometer (Figure 14), a method still used in the ceramic industry. The method is open to several objections not least being the high concentration required in order to obtain accurate readings.
