Abstract

Particle packing structure was evaluated using a polarized microscopy for tape cast alumina green body. Alumina particles of elongated shape were aligned with their long axis parallel to the tape casting direction. The overall particle packing structure was consistent with what was expected from the slurry flow under a blade. The sintering of the green body revealed a greater shrinkage in the thickness direction, which strongly related to the particle packing structure in the greeb body.
