Abstract

Experiments have been performed to determine the effect of water on dilute suspensions of CrO₂ in tetrahydrofuran (THF). The effect of water in the solvent as well as on the particle surface has been investigated using electrokinetic and dispersion stability measurements. Results of these investigations have shown that the zeta potential of dried CrO₂ (physisorbed water removed) in THF is positive and is dependent on the water content in THF. The zeta potential exhibits a maximum at about 1,800 ppm water. Good correlation also exists between the electrokinetic and dispersion stability measurements.
