SiC whisker-reinforced reaction bonded silicon nitride composites were fabricated by processing submicron Si powder and SiC whiskers in ethanol with the addition of a polyethoxylated amine. Potentiometric titration estimated that the equivalent weight of the amine additive was 1531 g/equiv. Adsorption of the additive did occur on the Si powder surface and it was Langmuirian in nature; the additive did not adsorb onto the SiC whisker surface. Rheologkal data for the Si-SiC whisker composite systems will be reported. Sedimentation studies determined that whisker packing densities in ethanol were 70% better than in aqueous systems. Composites formed by colloidal filtration were characterized for percentage of nitridation and for flexural strength.
