Abstract
The micro-columnar-structure in alumina was controlled by the process which consist of unidirectional solidification, freeze-drying and sintering of alumina-slurry. In particular, the effect of additives in the alumina slurry on the formation of columnar-structure was investigated. In the sample made from the slurry containing sodium chloride, the direction of columnar-structure of alumina was randomly arranged, while the columnar-structure was unidirectionally arranged in the sample obtained from the slurry without additives. On the other hand, the alumina sample obtained from the slurry containing ethylene glycol shows the micro-cell structure. The mechanical property in micro-columnar-structured alumina / unsaturated polyester composites was strongly depended on the width and spacing of columnar-structured alumina.
