• The effects of the addition of surfactants and of the surface treatment upon the aqueous dispersion of silicon carbide were examined. In the case of β-SiC, the addition of nonionic surfactants having relatively longer lengths of hydrocarbon and oxyethylene chain to the β-SiC treated with a silane coupling agent enhanced the dispersion stability. On the other hand, the lack of a difference for the dispersion stability was observed between a silane coupling treated α-SiC and an untreated one by the addition of surfactants. These differences in the surface property of two kinds of SiC were confirmed by measuring the zeta potential and the heat of immersion in water.
