Abstract
Dispersion characteristics of the Zhuravliny Log kaolin, zeta potential, and apparent viscosity of its suspensions were studied. Kaolin suspensions had rather high stability due to the negative charge of particle surface. Zeta potential was described as a function of pH and tripolyphosphate concentration by the electrophoresis. The additive influenced the apparent viscosity of suspensions for account of pH and zeta potential increase ability. Kaolin isoelectric point was found (3.28). Kaolin suspension had a sufficiently high casting rate that might be explained by a good mineral crystallinity (Hinkley index 1.76).
