Abstract
This investigation is to study the aggregate process and the structure of particles in high concentration slurry using slip casting. The aggregate state of the particles in an alumina slurry were discussed on the basis of rheological and sedimentation behavior. From these properties, this slurry could be classified into three states of aggregated structure as a function of the dispersant concentration. The structure of these slurries was observed directly by the freeze drying technique. The behavior of spinability of these slurries was discussed on the basis of this structure.
Simulation of the aggregate process of particles was done as a function of cohesion probability. Then, the relationship between the dispersion state of particles and the cohesion probability were showed.
From the results of the measurments, the dispersion state of the particles in these slurries were determined.
