Abstract

The objective of this study was to investigate the effects of temperature and solids loading on the viscosity of two non-aqueous ceramic suspensions. In this article, the viscosity of Al2O3 suspensions with 5%-50% solids loading and hydroxy-apatite suspensions with a solids loading of 5%-40% were measured at temperatures of 25°, 45°, 65°, and 75 °C. The high-shear Newtonian viscosity at various temperatures was reduced to a single curve by the reduced viscosity and the temperature-adjusted solids volume fraction of the suspensions. The Krieger-Dougherty model, with the intrinsic viscosity corrected for particle geometry, was fitted to the data and was observed to provide a satisfactory description to the solids-loading-viscosity data for both suspensions.
