Abstract

Results of a study of the rheotechnological properties of high-alumina suspensions with a granular silicon carbide filler are presented. It is shown that the rheological behavior of the suspensions changes with the introduction of the filler. The dependence of the effective and relative viscosities on the volume fraction of the filler is considered, and ηmin is calculated for systems with nonuniform chemical composition. The minimum viscosity of filled suspensions is shown to obey the Pivinskii equation for chemically uniform and nonuniform systems. The minimum distance between the filler grains is determined depending on the amount of the filler and its mean grain size.
