    The influences of suspension pH and the added amount of the cationic polyethylenimine (PEI) dispersant on the stability of SiC suspensions have been investigated by measuring their zeta potential, rheological properties and adsorption behavior. The PEI adsorption state on the SiC surfaces under different pH conditions played a key role in the modification of the particle surface charges and the stability of suspensions. The pH range of stable suspensions was determined depending on the added amount of PEI
