Abstract

Abstract: The surface properties of two different kinds of silicon carbide were studied. Though they have similar distribution of particle size, but their slurries show different rheological properties.Adding PEI into slurry of SiC-1 as a dispersant to form stable slurry is needed and the maximum solid content of SiC-1 slurry can reach as high as 40vol%. Another powder named as SiC-2 can reach its high solid content as much as 55vol% only by adjusting pH values.

Key words: silicon carbide, surface properties, rheological properties
