Abstract
The internal structure of yttrium-doped tetragonal zirconia powder compact was characterized using the immersion liquid technique, mercury porosimetry, scanning electron microscopy, and a compaction test. The specimens examined were prepared by pressing spray-dried granules at various pressures from 5–600 M Pa. The immersion liquid technique had numerous potential advantages, over the other methods for evaluating defects of 1–10 μm in size. With this technique, intergranular interfaces and pores were found to be present even in the specimen prepared at 600 M Pa. A feature, which is considered to be an agglomerate, was also found. The significance of the large defects on ceramic processing, as well as a comparison of the technique with the other methods, is presented.
