Abstract

Surface states of ceramic particles such as SiO(2), Al(2)O(3), Si(3)N(4) and so on suspended in aqueous alkaline solutions were successfully and easily determined by a potentiometric titration method. Isoelctric point, iep and excess surface charge density were classified and evaluated for many ceramic particles from the view points of aggregation and dispersion of particles and solubility in aqueous solution.
