Zeta potential is a key indior of the stability of the particle system. With a high zeta potential, the repulsive force between particles is strong and the system tends to be stable. Alternatively, with a low zeta potential, the repulsive force between particles is weak, the particles are easy to agglomerate or flocculate, and the system stability is poor.
highest positive potential is 40 mV (pH = 3.0). The sign of zeta potential is reversed from positive to negative at IEP [24,25]. In the pH range of 3–6 where the experiments were done, alumina and silicon carbide particles are oppositely charged. 2468 10 12 14-80 0
