内容简介

The optimum molecular structure of an anionic polymer dispersant in a Si_3N_4 suspension, to obtain high electro-steric repulsion force for the silicon nitride particles and low suspension viscosity was determined at the hydrophilic to hydrophobic ratio, m:n = 100:0. The addition of 5 wt% alumina particles to the aqueous Si_3N_4 suspension decreased the suspension viscosity for almost all conditions of the polymer dispersant added. The conclusions about the TiC/alumina study should be mentioned.
