Study of nanocrystalline gamma-Al2O3 produced by high-pressure compaction
Article Abstract:
Samples of gamma-Al2O3 were produced by compaction at 4.5 GPa in a toroidal-type device at room temperature and at higher temperatures using a high-pressure method. Compaction at room temperature provided crack-free, translucent and dense samples. These characteristics were enhanced for samples compacted at higher temperatures up to 565 degrees C. Findings support the hypothesis that the compaction at high-pressure caused the production of a strong structure, with closed pores containing trapped water and hydroxylated internal structures.
