Abstract
In this paper the packing density, shrinkage, theological and mechanical properties of clay/alumina mixtures are investigated. The packing density and shrinkage of clay during drying and firing is improved by adding alumina. Consolidated bodies formulated from mixtures of different amounts of clay and alumina exhibited plastic behavior during uniaxial compression. Flow behavior of particles in the slurry state was governed by the strongest third network- formed through the contact of alumina and clay particles- when both alumina and clay powder have similar particle sizes. For mixtures where large and small particles are in interaction the viscosity behavior of the slurry depend on the volume fraction of both constituents.
