The ζ-potential of cabon black particles was measured in dispersion media, such as various aqueous solutions of acids, alkalis, alkali-metal chlorides, sodium halides, surface active agents and alkyl amines. In measuring ζ-potential of carbon black particles, it was found that preparation method of sol, magnitude of current, calculating equation of ζ-potential and temperature worked as influential factors. These optimum factors on the measuring ζ-potential were already presented. In this experiment, the effects of electroviscosity, surface conductance and dielectric polarization on the ζ-potential of carbon black particles were studied. From the result obtained, it can be concluded that these effect on the ζ-potential were very small and could be neglected.
